00032 // Description: This file contains the class definition for RCM.
00033 // RCM is an object to perform the Reverse Cuthill-McKee numbering
00034 // scheme on the vertices of a graph. This is done by invoking the
00035 // number() method with the Graph to be numbered.
00036 //
00037 // Side effects: numberer() changes the Tmp values of the vertices to
00038 // the number assigned to that vertex.
00039 //
00040 // What: "@(#) RCM.h, revA"
