a) 0-1 knapsack problem is the use of dynamic programming method, the algorithm Thought as follows : some of the problems often no way to put them into a smaller number of sub-issues, in such circumstances, it attempts problem into the necessary number of sub- problems, every child that the problem can be divided into a number of uncertainties over the need for the children, this will have a lot of the problem. If the share of the sub- problems ill-defined, overlapping, in a large number of sub-issues there will be some identical son, thus the solution of such problems, it will be possible to repeat the same number of sub- problems solution. Such duplication is unnecessary. avoid the method can solve a problem for it to the solution (including his son, son of FNL) remain, if faced with
