Title: Calculation system for shortest route
Inventor: SUZUKI MICHIO
IPC: G06F17/10
Filed: 1985-09-20
Abstract: PURPOSE:To improve the processing efficiency for calculation of the shortest route by treating adjacent matrices where the relation between adjacent nodes is shown by the elements of '1' and '0' by means of logical operation of bits. CONSTITUTION:In a network consisting of nodes A-F, each element of an adjacent matrix ¦A¦ containing an element of '0' or '1' showing an adjacent state between two nodes is set at a single bit. Then the rows of the ¦A¦ are stored in the memory areas (1)-(6) with the columns stored in the memory areas (7)-(12) respectively. While areas (13)-(24) are set for arrivable matrices ¦R1¦-¦Rn¦ expressed by ¦Rn¦=¦Rn-1¦*¦A¦. The calculation of the arrivable matrix R2 is calculated by performing an operation for an AND corresponding to the bits of the 1st row (13) of the arrivable matrix ¦R1¦ (=¦A¦) and the 1st col umn (7) of an adjacent matrix ¦A¦ and then setting the arithmetic result at '1' since the contents of said register are not equal to '0'. A distance matrix is calculated by an equation based on the arithmetic result of the arrivable matrix. Thus is it possible to calculate the shortest route with small memory capacity and high arithmetic efficiency.
