Barrier function. In constrained optimization, a field of mathematics, a barrier function is a continuous function whose value increases to infinity as its argument approaches the boundary of the feasible region of an optimization problem. [1] [2] Such functions are used to replace inequality constraints by a penalizing term in the objective ...
