ABSTRACT:
The arrangement is formed by the presence in each node of the network of a cellular automaton comprising cells (0 to 8) interconnected by lines, so that the entirety of the cells and of the lines represents the nodes and the links respectively of the network while each cell comprises calculating means for calculating the cost of a path, works asynchronously, and communicates with each of its nearest neighbouring cells and only with them. When the arrangement is simulated in a sequential machine, this machine is programmed to choose the order in which the cells are activated on the basis of the minimum number of links to be passed through to connect two nodes, which nodes are determined by having the cellular automaton turn when the states of the links are mutually equal.
