In a rectangular grid, given two sets of nodes, S S sources and T T sinks , of size 2 Ε½ . each, the disjoint paths DP problem is to connect as many nodes in S S to the Ε½ nodes in T T using a set of ''disjoint'' paths. Both edge-disjoint and Β¨ertex-disjoint . cases are considered in this paper. Note

β¦ Synopsis
We consider the following problem: Given an integer k and a network G with two distinct vertices s and t , find a maximum number of vertex disjoint paths from s to t of length bounded by k. In a recent work [ 91 it was shown that for length greater than four this problem is NP-hard. In this paper we present a polynomial heuristic algorithm for the problem for general length. The algorithm is proved t o give optimal solution for length less than five. Experiments show very good results for the algorithm.

## This article presents a new heuristic algorithm called DDBMA (Dynamic Delay Bounded Multicast Algorithm) to construct a minimum-cost multicast tree. The heuristic depends on (1) bounded delay along paths from source nodes to each destination node; (2) minimum cost of the multicast tree; (3) dyn
