A simple game with a singular focal line. (English) Zbl 0666.90104

J. Optimization Theory Appl. (to appear).
We propose a simple game the solution of which contains a singular focal line, i.e., a focal line reached by optimal trajectories in a nontangential fashion. We also provide a discussion of how the optimal discriminating strategy can be approximated by a pure feedback.
