Optimization Algorithms

Linear programming problems are a highly desirable formulation for any practical problem. The reason is that, with the rise of interior-point algorithms, it is possible to efficiently solve very large problems (involving hundreds of thousands or even millions of variables) to global optimality. Linear programming optimization problems strictly fall under the category of deterministic global optimization. WebNov 29, 2024 · Photo by Noah Buscher on Unsplash.
