Abstract In this paper a fixed‐point solver for mappings from a simplex into itself that is gradient‐free, global and requires function evaluations for halving the error is presented, where is the dimension. It is based on topological arguments and uses the constructive proof of the Mazurkewicz–Knaster–Kuratowski lemma when used as part of the proof for Brouwer's fixed‐point theorem.
