Interior-point methods (also referred to as barrier methods or IPMs) are a certain class of algorithms that solve linear and nonlinear convex optimization problems. An interior point method was discovered by Soviet mathematician I. I. Dikin in 1967 and reinvented in the U.S. in the mid-1980s. In 1984, Narendra Karmarkar developed … Webb7 dec. 2024 · Interior Point Methods are often used to solve linear programming problems and can also be used to solve nonlinear programming problems. They typically employ a two-phase approach, with a first phase to find a feasible solution and the second phase to refine the solution to optimality.
