Gurobi R positive semidefinite matrix
Hi, I am solving a quadratic integer programming problem with Gurobi min x'Qx where Q = A'A, which mathematically should be positive semidefinite. In practice, however, sometimes gurobi R interf...

binary programming for 0/m instead of 0/1 variables
回答済みHi, I'm using Gurobi to solve an optimization problem min(x'Qx-c'x), where x is a vector that I need to figure out. Each element in x should be either 0, or some real number m, for example x = [0,m...
