0-1 integer Programming and implicit enumeration-feeling the charm of pruningInteger Planning is a special case of linear programming, that is, when the constraint is a variable integer, the linear programming becomes the integer plan. If all variables are required to be integers, it is a pure integer plan ; If some of the variables are allowed to be integers, it is called mixed integer planning . the

Simple descriptionThe 0-1 knapsack problem is described as follows:There is a backpack with a capacity of V, and some items. These items have two properties, Volume W and value V, and only one for each item. Ask for the maximum value of the item that is worth as much as possible with this back, and the backpack may not be filled. Because there are two possible cases for each item in the optimal solution, ei
