Abstract
In this paper we introduce and develop the notion of simple close curve magnetization.
We provide an application to Bellman’s lost in the forest problem assuming special
geometric conditions between the hiker and the boundary of the forest.

Introduction and Problem Statement
Bellman’s lost in the forest problem is a central problem which lies at the interface of geometry and optimization. It has
its origin dating back in 1995 by the American applied mathematician Bellman (1956). The problem has the following
well-known formulation which can be found in Finch and Wetzel (2004).
Question 1 (Bellman’s Lost in the Forest Problem): Given a hiker in the forest with his orientation within the forest
unbeknownst to him, then what is the best possible decision to be taken to exit in the shortest possible time taking into
consideration the shape of the forest and the dimension of the space covering the forest?
Much work has been done in studying this problem by a few authors (see Ward, 2008). This presumably has not to
do with diminished interest and less popularity but may partly be attributed to the conceivable complexity of any viable
tool to studying the problem. Regardless of its inherent difficulty a complete solution has been found and is known for
a few class of shapes which are taken to be forest (Ward, 2008).
In this paper we introduce and develop the notion of magnetization of simple close curves. Using this notion we
devise an algorithm that takes as input the shape of the forest and the dimension within which the forest resides and
produce as output the optimal path to be taken by the hiker v

2. Simple Close Curves with Magnetic Boundaries
In this section we introduce the notion of simple close curve with magnetic boundaries equipped magnets. We study
this concept and expose some connections with other notions.
