It is assumed that there are no source-to-source or sink-to-sink loops.
The input is read from stdin and output is written to stdout.
Two types of output are reported:
For each parameter value, the elapsed time (since reading the input file) and the corresponding min-cit value are reported.
For each node, the parameter number at which the node entered the source set is reported (for example, if a node was in the sink set for the (j-1)-th parameter and is in the source set for the j-th parameter, the parameter number "j" is associated with that node). The source by default enters the source set at parameter number zero. If there are "k" parameters, the nodes in the sink-set corresponding to the k-th parameter are assigned a parameter number of (k+1). The sink is assigned a parameter number of (k+2).
