Title Link: BZOJ-1221Problem analysisAlgorithm one: Minimum cost maximum flowFirst, this is a classic network flow problem. Create two nodes per day, one I means using towels, and one I ' means the towel used this day.Then I to T even Ai (the number of towels needed for the first day). From S to I ' Even AI, so the new used towel this day is AI.Then I ' can be connected to (i+1) ', said to stay until the next day to deal with, I can also flow to i+p+1
A matrix is given with a constraint: I (0
At first glance, we built a bipartite graph. However, we found that there was a lower bound and no upper bound minimum cost flow problem... Problem conversion: the so-called difficult is opposite! At present, a row/column must have at least K rows and at least the sum. Isn't that row/column having at most K rows and column having the maximum sum? In fact, that is, a maximum of K is used to convert the maximum

Question at a glance ..
The connection capacity of each source is 1 and the cost is 0.
Each person connects to a transit node with a capacity of 1 at a cost of 0 (you can also directly connect to the back end without connection)
The transit node Na wants to connect all items A with a capacity of 1 at a cost of 0.

Cross entropy cost function 1. Cross-entropy theory
Cross entropy is relative to entropy, as covariance and variance.
Entropy examines the expectation of a single information (distribution):
H (p) =−∑I=1NP (xi) Logp (xi)
Cross-Entropy examines the expectations of two of information (distributions):H (P,Q) =−∑I=1NP (xi) logq (xi)For details, please see Wiki Cross entropy
