图2是一个示例,在该模型中变量 x1,x2,...,xn 如果是连续值,则该模型为线性规划模型(Linear Programming);如果是整数(在很多问题中变量会是0-1变量(binary variables)),则该模型为整数规划模型(Integer Programming),如果两者都有,则称其为混合整数线性规划(Mixed Integer Linear Programming)模型。 图2(被水印...

GLOP cannot solve ILP problems, but other solvers can. Actually, a lot of them aremixed integer linear programming(MILP, commonly called MIP) solvers. This means that they can consider bothcontinuous(real numbers) anddiscrete(integers) variables. A particular case of discrete values is Boolean va...
In some linear programming problems it is required of the optimal solution that the variables, or some of them, should be non-negative integers (0, 1, 2, ...), the interpretation of the problem being such that fractional values would be meaningless or irrelevant. For example, a commodity ...
