$Sol$
This is one having a plurality of "volume dimensions" $ 0 / $ 1 knapsack problem.
The $ N $ N $ $ considered as candidates number items, each item has the following three volumes:
1. "number" of each candidate "number" is $ 1 $, and ultimately to fill the volume of $ M $ backpack
2. "defense score", $ A [I] $
3. "anti-party score", $ B [I] $
The defense is required out of $ D $ and $ P $ prosecution out the absolute value of the difference between the $ | the DP | $ minimum, if the selection method is not unique, then select $ D + P $ maximum program
Therefore, the $ a [i] -b [i ] $ as one volume, the $ a [i] + b [ i] $ as the value of the article
Note here $ a [i] -b [i ] $ may be negative, so that uniform plus $ 4000 $
In consideration of the $ I $ individuals stage, $ f [j] [k ] $ $ I $ denotes have been previously selected for Custom $ J $ individuals, this time difference is out of both of $ k $ time , both of the maximum score.
$f[j][k]=max(f[j][k],f[j-1][k-(a[i]-b[i])]+a[i]+b[i])$
Since the required output scheme, the array plus a $ d [i] [j] [k] $ denotes $ f [i] [j] [k] $ $ I $ of candidates is not selected from the group selected from the group, so that the recording program.
