Hello Jaromil, Thank you for replying to my request! The piecewise linear approximation I need to put in Gurobi model is of function ln(x). Since x cannot take 0 as a starting point, I need to set...

Problem with gurobi default setting for piecewise linear function
AnsweredHello, I'm using this piecewise linear function in gurobi. for i in range(N+1): for k in range(M): m.addGenConstrPWL(q[i,k],u[i,k],u_axis_x,u_axis_y) for k in range(M):...
