NODE DISJOINT PATH FORMING METHOD FOR HYPERCUBE HAVING DAMAGED NODE

A node disjoint path forming method for a hypercube having a damaged node which is capable of using unused nodes (surplus nodes) in an n-number of node disjoint paths each having a length of n with respect to n-dimensional hypercubes more than 4-cube, so that it is possible to obtain an n-number of node disjoint paths each having a length of n even though there are damaged nodes. The method includes the steps of a first step for forming a linear arrangement consisting of an n-number of integers (0, 1, 2, . . . n-1) with respect to an n-dimension and searching a linear arrangement which is not neighbored in a linear arrangement in which integers which indicate a value of 1 in an address of a damaged node are circulated, assuming that a node address with respect to an n-address is expressed as a position of 1 among an n-number of binary digits, separating each value by a comma by defining an address value of a decimal digit indicating a position of 1 using a bracket, defining the rightmost position as 0 and the leftmost position as n-1, and a second step for forming a linear arrangement using integers of an arrangement in which values indicating a position of 1 in an address of a damaged node are not neighbored on a circumferential portion, moving the linear arrangement by one digit in the right direction and forming an nxn first matrix.
