Homotopic continuation
WebIt should be strongly remarked that this does not have anything in common with the techniques of homotopic continuation. Homotopy is powerful since it only makes use of the concept of continuity and thus it is applicable to general smooth nonlinear systems, but on the other hand it does not always provide a reliable method to approximate the … WebDiscrete continuation method (DCM) is a widely used homotopy method to solve optimal control problems. Starting from auxiliary problem, DCM monotonously varies homotopy parameter until the objective problem is solved. However, DCM often fails when the initially and manually defined homotopy path exists limit points or goes off to infinity.

WebFor λ = 1, is the original problem (1). The parameter λ is called the continuation or homotopy parameter. H (x, λ) = (1 - λ)G (x) + λF (x). (6) is the original problem. By following solutions of. as λ varies from 0 to 1, the solution to F (x) = 0 is reached. The solutions (9) trace a path known as the zero curve. WebMoreover, the homotopy continuation method has been also used to explore the general parameter space, so-called paramotopy, as a quite powerful tool for many classes of problems that arise in practice [3]. In the linear homotopy setup, each solution path can be tracked via the prediction/correction algorithm [6, 14, 18] which
