"WebA new technique is developed to optimize continuous medium- and low-thrust orbit transfers. This approach combines large-scale linear programming algorithms with discretization of the trajectory dynamics on segments and a set of pseudoimpulses or control for each segment. The set is a discrete approximation with a small mesh width for a space of possible thrust … " - Infeasible interior point method

WebOne of the most successful paradigms for solving LPs is the family of Interior Point Methods (IPMs), pioneered by Karmarkar in the mid 1980s [25]. Path-following IPMs and, in particular, long-step path following IPMs, are among the most practical approaches for solving linear programs. Consider the standard form of the primal LP problem: WebThe method uses the function ψ(t) = t2 in order to determine the new search directions and performs only one feasibility step in a main iteration. In fact, our method is an infeasible version of ...
