<p>A polynomial time algorithm for solving the combinatorial problem that underlies the reconfiguration issues in the m1/2-track-m-spare model, for any arbitrary m, is discussed. The following combinatorial problem is solved: Given a set of points in a two-dimensional grid, find a set of noninteracting straight lines such that every line starts at a point and connects to one of the boundaries of the grid, there are no more than m lines overlapping in any row or column of the grid, and there are no near-miss situations. The time complexity of the algorithm is shown to be O(m mod F mod /sup 2/), where mod F is the number of faulty processors.</p>
