CS/ECE/ISyE 524 Introduction to Optimization L. Roald, Spring 2022

Consider a simple instance of this problem, where C_{max} = 500 and _{1} = _{2} = _{3} = _{4} = 1. Also assume for simplicity that each variable has a lower bound of zero and no upper bound. Solve this problem using JuMP. Use the Ipopt solver and the command @NLconstraint(…) to specify nonlinear constraints such as logsumexp functions. What is the optimal T , r, and w?
