Web1 With X a vector of binary variables, and W a vector of float variables, I want to write a constraint such that if W [i] > 0, then I should have X [i] = 1. dvar boolean X [I]; // we choosed stocks i or not dvar float W [I]; // weight of stocks i in portfolio How can I state this constraint? cplex portfolio opl Share Improve this question Follow Webdvar int x in 2..10; dvar boolean b; maximize x; subject to {b*x<=7;} but they get CPLEX Error 5002: 'q1' is not convex. and that is quite normal. What can they do ? 1) Use CP: using CP; …
