WebJul 14, 2024 · To address this shortcoming, we derive stronger formulations that scale well with respect to the problem size. Our focus is on ambiguity sets under the so-called left-hand side uncertainty, where the uncertain parameters affect the coefficients of the decision variables in the linear inequalities defining the safety sets. WebWe propose new robust models for handling right hand side uncertainty in linear problems. A cutting plane-like method could be devised to solve the resulting robust problems, but the subproblem to solve at each step involves a bilinear objective. Upper approximations are thus constructed based on linear decision and zero-order rules on the ...
