Different objective functions on different domains
AnsweredHi, My objective function is given below where the domain in y is [0 120] and x is [0 1]. However, this funcion is hard to model in its original form due to many exponential and product of exponent...

Function approximation of a complex objective function
AnsweredHi, I would like to approximate the following objective function using a simpler function that can use be defined in gurobi. \begin{equation}\min_{I_{i,v}} \ \sum^{N_v}_{v}\sum^{TT_v}_{i} \ C_{loss...

addgenconstrlog() constraint value is different from math.log value (Similar issue with addConstrExp( ) ))
AnsweredHi, The m.addGenConstrLog(x,y) output result is not y = ln(x). m.addGenConstrExp(x,y) output is not y = e^(x) I am trying to solve the following problem. But I keep getting Model is infeasible err...
