Abstract The paper presented a fixed-size systolic system for the transitive closure and shortest path problems. The system can solve an arbitrarily large size matrix by partitioning it into smaller submatrices that fit the fixed-size systolic arrays. Equations for the execution time, area-time prod...
Summary: A description is presented of a cell automaton in the form of an $n imes n$ matrix of cells exchanging signals with its nearest neighbors in a solution of a search problem for a transitive closure and the shortest distances of an n-vertex graph after O(n) cycles of operation. ...
