## Bellman’s Escape Problem for Convex Polygons

**Authors:** Philip Gibbs

Bellman’s challenge to find the shortest path to escape
from a forest of known shape is notoriously difficult. Apart from a
few of the simplest cases, there are not even many conjectures for
likely solutions let alone proofs. In this work it is shown that when
the forest is a convex polygon then at least one shortest escape path
is a piecewise curve made from segments taking the form of either
straight lines or circular arcs. The circular arcs are formed from the
envelope of three sides of the polygon touching the escape path at
three points. It is hoped that in future work these results could lead
to a practical computational algorithm for finding the shortest escape
path for any convex polygon.
