Chases and Escapes, and Optimization Problems
  We propose a new approach for solving combinatorial optimization problem by
utilizing the mechanism of chases and escapes, which has a long history in
mathematics. In addition to the well-used steepest descent and neighboring
search, we perform a chase and escape game on the "landscape" of the cost
function. We have created a concrete algorithm for the Traveling Salesman
Problem. Our preliminary test indicates a possibility that this new fusion of
chases and escapes problem into combinatorial optimization search is fruitful.
