dijkstra

DIJKSTRA(1)						      General Commands Manual						       DIJKSTRA(1)

NAME

       dijkstra - single-source distance filter

SYNOPSIS

       dijkstra [ -ap?	] [ sourcenode file ]

DESCRIPTION

       dijkstra  reads	a  stream  of  graphs  and  for each computes the distance of every node from sourcenode.  Edge length is given in the len
       attribute, and the default is 1.  The dist attribute of every node is set to its distance from sourcenode.  If the -p  flag  is	used,  the
       prev  attribute	of  each  node	reachable from sourcenode is set to the name of the previous node on a shortest path.  The graph attribute
       maxdist is set to the maximum dist of all nodes in the graph.

       By default, if the graph is disconnected, the dist attribute of nodes unreachable from sourcenode are left untouched, and maxdist is set to
       the  maximum  of  any  previous	value  and  the largest distance recorded in this run. On the other hand, if the -a flag is used, the dist
       attribute of an unreachable node is assigned a very large value, and maxdist records the maximum distance found in the component containing
       sourcenode.

       Any number of sourcenode file pairs may be given.  If the last file is missing, stdin is used.  All output is written to stdout.

       In a typical application, dist and maxdist can drive a downstream calculation of color or some other attribute.
