WebJan 1, 2024 · The relax-and-fix algorithm builds an initial solution for the problem, while the fix-and-optimize algorithm improves it. We first present pre-processing and simplification procedures to reduce the model’s total number of variables and constraints. WebThe optimization algorithms can be roughly divided into local optimization algorithms which find a nearby local minimum and global optimization algorithms that try to find the global minimum ...
