NettetThe starting value must be in the interior of the feasible region, but the minimum may be on the boundary. A logarithmic barrier is added to enforce the constraints and then optim is called. The barrier function is chosen so that the objective function should decrease at each outer iteration. sphn590rNettet1. jan. 2024 · In this paper we consider optimization problems with stochastic composite objective function subject to (possibly) infinite intersection of constraints. The objective function is expressed in terms of expectation operator over a sum of two terms satisfying a stochastic bounded gradient condition, with or without strong convexity type properties. sphn440w-ds 特徴NettetAn important subset of optimization problems is constrained nonlinear optimization, where the function is not linear and the parameter values are constrained to certain … sphn440w
