The solution of the problem has developed the many classic methods, the exploration and application research has been in. Under the guidance of advanced theory, solving 0-1 knapsack problem has significant characteristics of scientific and efficient, economic, flexible, convenient and so on. So to solve the knapsack problem, the first premise is to design a good algorithm, to obtain the solution of the knapsack problem, we must first design algorithm, based on Backtracking knapsack problem, complexity analysis of the algorithm design and 0-1 knapsack problem and the simple 0-1 knapsack problem, the specific design and implementation process and algorithm is given. With concrete examples with different methods are described to solve the algorithm the basic idea, and then solve the 0-1 knapsack problem for a detailed comparison of the four algorithms, to achieve the advantages and disadvantages of this method and summarizes the conclusion. How will the knapsack problem is applied to practical problems, to design suitable for solving 0-1 knapsack problem the algorithm, and it is quite good to solve practi
