well I know what the states of the dp are but I don't know how to calculate them efficiently or how to transition between them there are n.m.16 states consider a cell x,y then it has an edge with x - 1, y, x + 1, y , x, y + 1, x, y - 1 so in total 4 edges and 2^4 possible subsets (think each edge on and off) since there are n.m cells so in total n.m.16 states

I may be wrong though.
