Abstract

In this work, an active set strategy is used together with a Coleman–Li strategy and
penalty method to transform a general nonlinear programming problem with bound on the variables
to unconstrained optimization problem with bound on the variables. A trust-region globalization
strategy is used to compute a step. A global convergence theory for the proposed algorithm is pre-
sented under credible assumptions.
Prefatory numerical experiment on the algorithm is presented. The rendering of the algorithm is
reported on some classical problem.
