WebMar 25, 2024 · What I've tried is a somewhat sloppy model of the problem in Gurobi so far. I'm not sure how to correctly index and iterate through my sets that are required to produce a result. This is my main problem: The objective function I define to minimize transport costs is not correct as I produce a non-answer. The code "runs" though. WebMay 20, 2024 · Hi Livia, To model the \(2^z\) function, you have to use Gurobi general constraint interface. In your particular case, you have to use the genconexpa struct array.There is no example showing exactly this function but the gc_pwl_func.m example shows the usage of the genconexp struct array, which works analogously..

WebFeb 1, 2015 · 1 Answer. Sorted by: 4. For a somewhat complex causal chain d [ (x,y)] in your code is equivalent to d [ (0,1)], so the constant -5 winds up being your objective function. The reasons are. gurobi.Var has __hash__ defined. gurobi.Var has __cmp__ defined. It always returns a truthy object. In your case, x and y have hash values of 0 and 1. WebGurobi is used in dozens of industries and by over 2,400 companies.
