Abstract:The rectilinear/octilinear Steiner problem is the problem of connecting a set of terminals Z using orthogonal and diagonal edges with minimum length. This problem has many applications, such as the EDA, VLSI circuit design, fault-tolerant routing in mesh-based broadcast, and Printed Circuit Board (PCB). This paper proposes an obstacle-avoiding 4/8/10/26-directional heuristic algorithm for this problem based on the Areibi's concept, Higher Geometry Maze Routing, and Sollin's minimal spanning tree algorithm.
