Construction of a shortest path around semi-algebraic obstacles in the plane
T. Krick, A. O. Slissenko, P. Solernó, J. Heintz
Abstract:
The authors describe an algorithm that in polynomial time reduces the problem of finding a shortest path (between 2 points) not intersecting semi-algebraic obstacles in the plane, to the problem of finding a least cost path in a graph which vertex cests are integrals of positive algebraic functions (without singularities). As a consequence one gets an algorithm which in time polynomial in the leagth of input and $1/\varepsilon$, constructs an $\varepsilon$-approximation to a shortest path. Related problems and results are briefly discussed.
