1) When bruteforcing, random shuffle both m rows and n ships

2) When solving one subset sum problem inside bruteforcing, use bitset (array of bitsets) instead of bool array (2d-array). Instead of max() in subset sum problem, use operator OR and operator "right bit shift". Just search "subset sum problem bitset" and you'll find out. This will speed up your dynamic programming in 32 or 64 times (if you are using both 64-bit compiler and 64-bit processor)

It will not totally solve problem, but you will get TLE#67 which is better and giving more hope :)
