WebProblem: Optimize f(x) subject to A(x) ≥0, x ∈D B & B - an instance of Divide & Conquer: I. Bound D’s solution and compare to alternatives. 1) Bound solution to D quickly. • Perform quick check by relaxing hard part of problem and solve. ÎRelax integer constraints. Relaxation is LP. 2) Use bound to “fathom” (finish) D if possible. a. WebThe proposed capacity allocation optimization method is a bilevel mixed-integer linear programming model, which is solved by the reconfiguration decomposition algorithm. The nonlinear constraint problem due to the physical characteristics of the hydrogen storage device is solved by the Big-M method and the binary method.
