I've implemented it (in PHP :P )

I'm seeing a rapid increase in time as letters are added.

But it's not immediately obvious whether it's a polynomial or a slow exponential, until I'm too tired to do the eye-balling. A sample of 281 letters had 14 seconds. 50 letters had 0.01 seconds. 100 letters had 0.25 seconds. 150 letters had 1.3 seconds.

Or, more succinctly:

I'm still having trouble accepting the claim of NP-completeness. Here's my next idea that I think runs in polynomial time. It's not a good polynomial (possibly n^3 or even n^4), but the NP property of the algorithm has to rest in a single level - if we can show that a step is repeated n^j times, and is n^k big, we are still in Polynomial complexity in total.

------

1. Generate my triangle matrix outlined above - O(n^2)

2. Examine the diagonal i=j+a (i is column, j is row). a is 1 in this first cycle. Complexity O(n) as there are less than n such diagonals.

2.1 Examine each value M(i,j+a)=1 in the diagonal. Call this point M(x,y). Complexity O(n) as the diagonal is less than n long.

2.1.1 Examine the triangle of values described by i>j and i<x and j>y. (In graphical terms, this is the triangle between the diagonal and the point to the lower left of M(x,y) ).

In the beginning this triangle is empty and the step can be skipped. At the end, this triangle contains at most half the matrix and thus takes O(n^2) to search.

2.1.1.1 Find the largest value inside the triangle.

2.1.2 Set M(x,y) to this largest value + 1.

2.2 Repeat step 2 with a = a+1.

3. Search through the matrix to find the largest value. This has complexity O(n^2) again.

4. Return the largest value, and have some coffee. Aaah.

I'm telling you, it's polynomial in the worst case! :P

Wait wait wait.

Do you know how we solved a labyrinth in FORTRAN, entirely without backtracking? We passed over the entire field, beginning at the entrance, and set each field unexplored field (value "0") adjacent to an explored field (value >0) equal to the value of the explored field + 1. This way, each field of the labyrinth had the minimum number of steps required to reach it. A long path might still take almost n^4 calculations (Longest theoretical path is n^2 steps, and each step requires a loop over the n^2 board), but we got rid of the backtracking and recursion.

Perhaps we can "accumulate" a solution here too? By incrementing all the values in the rectangle shown in the last post by 1... the only problem is that the rectangles overlap...

Edit:

To make clear how the matrix visualizes the solutions, here is another image that shows the matches we are looking at with X instead of 1:

dintiradan

d 1000000X00 dinid
i 100X00000
n X0000001
t 1000000
i 100000
r 10000
a 1010
d 100
a 10
n 1

dintiradan

d 1000000X00 ditid
i 100X00000
n 10000001
t X000000
i 100000
r 10000
a 1010
d 100
a 10
n 1

dintiradan

d 1000000100
i 100100000
n 1000000X nadan
t 1000000
i 100000
r 10000
a 10X0
d X00
a 10
n 1
Obviously, whenever we pick a certain 1 as a starting place, we then look at the triangle below and to the left of this position. There is still the problem of identifying the most promising place - look at the current example, where merely looking at the outmost matches wouldn't have helped us find which solution was better. If it were "Dintiraden", the "nadan" solution would not exist, but we couldn't have known it from the outmost matches:

dintiraden

d 1000000100
i 100100000
n 10000001
t 1000000
i 100000
r 10000
a 1000
d 100
e 10
n 1
Perhaps we should instead start at the other end, where we know we must end up? Start on the main diagonal or all those 1 positions that lie adjacent.

In this case, whenever we consider a certain position, what is left is not a triangle, but a rectangle - above and to the right of the position we're looking at.

dintiraden

d 0000100
i 0100000
n X
You then have to pick another match out of the triangle that's left, and repeat the process.

This process might still take polynomial time, though - if the problem is provably NP-complete, there's no way around that.

I think better in terms of numerical operations than character comparisons. Perhaps we can reduce the problem (requiring at most quadratic time, which is still less than the current solutions) by first comparing all characters with each other and building a boolean matrix:

I'll vainly demonstrate on my name:

arancaytar

a 1010010010
r 0100000001
a 1010010010
n 0001000000
c 0000100000
a 1010010010
y 0000001000
t 0000000100
a 1010010010
r 0100000001
I believe that in this matrix, we can, navigating through rows and columns, find the longest possible chain. I still need to figure out how, but I posted this here to give you all a little nudge in a direction that might show promise.

This is brainstorming, not a formal description:

If we do not need to work in place, I'd first make a copy of the string that is stripped of case and non-alpha characters. This is only a single pass over the string - O(n) - and takes at most as much memory as the string. This would greatly simply the analysis as we don't need to account for spaces or case any more.

I would then try to find potential center positions first - two characters that are consecutive, or one that is sandwiched between the same characters.

- For each character from 0 to length of string
--- Is next character equal to this character or to previous character?
--- Store the current index in a collection of potential palindromes.

This step can be done in a single pass over the string and is O(n).

(We need to store the information whether this is an even or odd length palindrome, and I can think of no elegant solution but only a special case checking. The following assumes an odd-length palindrome for simplicity.)

Next, we eliminate these candidates by extending each and finding out how long they get.

- Start i at 1
- While there are still values in the collection
--- Increment i
--- For each value in the collection
----- Compare characters at distance i in both directions from the value
----- If they're not equal (or one of the positions compared lies outside string boundaries), eliminate this value
- The longest palindrome (still assuming odd length) is (i-1)*2+1.

Because this algorithm identifies all candidates first and eliminates this tree of possibilities in Level Order, it is most efficient on a string with few such candidates or even just a single long palindrome. In that ideal case it could be practically linear. The worst case scenario is a string of equal letters. In this case, all letters are potential candidates and will be examined until each reach the edge and only the center is left, causing it to become O(n^2).

An alternative solution would be to eliminate each candidate completely in their own order, starting at the ones closest to the center (most room to expand). This would be faster in some cases but slower in others - I'm not sure how common each of these cases far.

--------------------------------

Gah. Tired. I hope I haven't just excreted complete nonsense.

I can use PHP and Java equally well, but I have more practical experience with PHP. I have programmed in FORTRAN, but it's been a while and I'd need to consult a book to make anything more complex than Hello World.

These aren't programming languages, but I can handle XHTML/CSS quite well (only basics of Javascript though).

All my current work is in PHP. I contribute to Drupal, and I work on some personal PHP websites, Endeavor and the PPP forum archives. Lately, I made this tool. I also like to implement primitive encryption ciphers (here).

I've told this story far too often, so "2003-05-20", "15 years" and "Avernum 3 didn't work in NT" are the condensed version.

All of these numbers are counted backwards from the number of my posts on PPP. About 800 are missing from there, so the number quickly becomes extremely inaccurate.

#1: Tech support question
#60: "note to self: never visit desperance if I value my sanity" (I chose this post because it represents a pearl of insight amid an embarassing mass of crap).
#92: I wrote a long ballad about Erika Redmark, which had some second-language idiosyncrasies, but with some editing is better than most of the poetry I've written since then.
#120: I "explain" the four-fold system of alignment (or "D&D Political Compass") as best as I understood it (I had first heard of it days earlier). Funny how odd "good chaotic" now sounds to me - since then I've learned that Lawful/Chaotic comes before Good/Evil.
#122: I "intend to read Phillip Pullman again in 10-20 years to see if my outlook changed". Awesome - it didn't take 5 years, and I didn't even need to read it again.
#169: I make a contribution of debatable value to a political discussion topic, the aftermath of which is the source of the name of my blog.
#206-#260: Build-up to what will eventually become...
#261: The Encyclopædia Ermariana, first mentioned online. (Pretentious ligature since dropped from title.)

(... oh ye gods, I'm so dumb. This is painful to read. So many hundreds of posts, so many emoticons, so much idiotic spamming. At least about 400 posts are missing from this time, and I have no particular urge to see them again.)

#979: My first ever RP post!

#1053: We reach some ugliness again. Sorry Johnnyfeds. You've annoyed me on AIM a few times, but that was out of line.

But I got my comeuppance - if memory serves, Djur gives me a good smack a few pages later... (which has disappeared though - all that remains is the first reference to "Elfy McSpamface").

"I'd make a terrible mod."

The graph shows a correlation that the data actually possesses.

You could use this to form a hypothesis that socialists are (with exceptions) more likely to be libertarian, while authoritarians prefer capitalism, indicating that the one-dimensional system might not be completely flawed.

But it's more likely that the test causes this bias (not a bias in a direction, but along a particular regression). You can't map viewpoints easily...

The corollary that conservatives tend to believe in the supernatural (and hence in astrology) is hilariously wrong.

Since the image is dynamic, it no longer matches the text. I've added all the historic data of Spiderweb - and as you can see, although the individual members move around a lot, we haven't significantly changed over the last four years.

One outlier is removed, namely VCH's 9 / 9.15 in December 2005. With my new expertise I could calculate both the likelihood of such a result within this community, and the likelihood when compared with his previous -3.88 / -5.23 and current -5.25 / -6.97; but the sarcasm sensor works just fine without number-crunching. :P

(This post starts out unrelated to the topic. I'm getting there, so be patient.)

Turns out that a week without internet access, a head full of statistics, and hands full of time that ought to be spent on exam revision, can make me kind of inventive.

This small PHP utility is an older work I made years ago; I just cleaned it up a bit this time. I started out making a horrible plotter for the (long-defunct, replaced by PPP) forum stats monitor; it's used in a (currently broken) obscure feature of the Endeavor that shows a bar graph of individual post count over time. I put some work time into it when my boss wanted graphical stats somewhere, but it took too long for him (that would have been a precious week wasted not repositioning submit buttons in web forms!) so he made me stop.

Essentially, it's a really simple to use (with basic PHP skill) tool to plot x/y data as a graph.

So when I finished fixing it, I gave it some old PC data I had archived (having no internet, after all), and here's the result:

The horizontal and vertical lines are mean values. Ellipsis around the mean center signify standard deviations. This gives - within the technical limits of the PC - an overview of the political position and variation different communities have.

I've also made a web form for adding to the map, but it's not quite done yet. Anyway, I'll replace the demonstration data with the stuff from this thread soon. :)
