Two Efficient Methods for the ZAB-Frogs Grid Path Problem
We consider a rectangular grid of size \(n \times m\) with a start cell \((s_x, s_y)\) and an end cell \((e_x, e_y)\). There are \(s\) "bad" cells that act as centers of circles with equal radius \(R\). A cell is blocked if its Euclidean distance to any bad cell is \(\le R\). The goal is t...
