[gcj] Can anyone explain the result of the following input of Problem D in Round 2?
I used the dynamic programming approach to solve the problem, but my program failed at the following input for large data: 7 36 The correct output is 16 while my output is 24. This test case could be reduced to the input of 7 12 where the correct output (by the programs from others) is 16 and my output is still 24. However, when I try to check the result by hand using the following representation: Block A2 (period = 1) Block B3 (period = 4) 222122212221 212121212121 212221222122 Block C2 (period = 3) 221221221221 221221221221 Block D2 (period = 6) 21111222 1111 Block E1 (period = 1) I get the following results: Input 4 12 Output 5 (Correct) 1: A2 + C2 2: A2 + D2 3: C2 + A2 4: D2 + A2 5: E1 + A2 + E1 Input 5 12 Output 7 (Correct) 1: A2 + B3 2: A2 + E1 + A2 3: B3 + A2 4: C2 + A2 + E1 5: D2 + A2 + E1 6: E1 + A2 + C2 7: E1 + A2 + D2 Input 6 12 Output 21 (Correct) 1: A2 + C2 + A2 (p3 +) (Note: p3 means period = 3, + means ended with A2) 2: A2 + D2 + A2 (p6 +) 3: A2 + E1 + A2 + E1 (p1) 4: B3 + A2 + E1 (p4) 5,6,7: C2 + A2 + D2 (p6) 8,9,10: C2 + A2 + C2 (p3) 11,12,13: D2 + A2 + C2 (p6) 14,15,16,17,18,19: D2 + A2 + D2 (p6) 20: E1 + A2 + B3 (p4) 21: E1 + A2 + E1 + A2 (p1 +) Input 7 12 Output 24 (Incorrect) 1: A2 + B3 + A2 (p4 +) 2: A2 + C2 + A2 + E1 (p3) 3: A2 + D2 + A2 + E1 (p6) 4: A2 + E1 + A2 + C2 (p3) 5: A2 + E1 + A2 + D2 (p6) 6,7,8: B3 + A2 + C2 (p12) (3 combinations) 9,10,11,12: B3 + A2 + D2 (p12) (4 combinations) 13,14,15: C2 + A2 + B3 (p12) (3 combinations) 16,17,18,19:D2 + A2 + B3 (p12) (4 combinations) 20: C2 + A2 + E1 + A2 (p3 +) 21: D2 + A2 + E1 + A2 (p6 +) 22: E1 + A2 + C2 + A2 (p3 +) 23: E1 + A2 + D2 + A2 (p6 +) 24: E1 + A2 + E1 + A2 + E1 (p1) I still cannot figure out what cases among the 24 I listed are duplicated or wrong.

Re: [gcj] a Linear Programming approach to problem B of round 2
Check out my (linguo, 36th) solution to C-Large. Python solution using linear programming tool. Make that runnable on your machine and you could do the same.

I think, GNU Octave + GLPK are acceptable tools in this contest (as both of them are open-source and free), so solving a LP (and MILP) problem is as hard as filling three matrices and calling one function. Correct me if I am wrong. Obviously you are right. A few questions, if you may: 1. Do you know if octave and GLPK run smoothly on windows? Never heard of GLPK and I always had the impression that Octave is only for linux, but I search around and see that I may have been wrong about that. 2. Is it possible to call such methods from another language? Specifically python, which is my bestest and most favorite language of use? Is it easy? 3. Is it possible to have complete accuracy in octave/glpk when handling fractions? I have that option in python using the Fraction class, but I am not sure how many other languages have such classes...

Re: [gcj] a Linear Programming approach to problem B of round 2
Indeed I did. The linear programming library I used did not give accurate
enough answers on the small data set to pass, so I solved the dual problem
instead, which turned out to be quite easy.

During round 2 I recognized that problem B can be described as a Linear
Programming problem.
There are two restrictions:
R_1 * t_1 + ... + R_n * t_n = V
C_1 * R_1 * t_1 + ... + C_n * R_n * t_n = V * X
t_1, ..., t_n are all non-negative
Finally the objective is:
Minimize (max{t_1, ..., t_n} )
That's quite a regular LP problem.
I know that obviously coding a solution to LP is much harder than the
simple analysis of this specific problem. Nevertheless, I was wondering –
did anyone tried to solve it this way? I know that LP might need more time
to solve. Is it doable in the GCJ time constraints (i.e., does it take less
than 8 minutes to get the full output?) Does anyone know?
