Step 2
Set n = lVlglobal
Step 3
If n represents the state with no unmapped task, with the
smallest value of f among all OPEN nodes, or the number of
new additions to the state-space equals nodecount then send
this optimal mapping (lVIlocal) to all parallel graph-matching
tasks. Also wait for others to send in their lVIlocal. Find the
mapping with minimum value of lVIlocal and set it to lVIglobal.
If lVIglobal has no unmapped tasks, this is the desired optimal
task. Otherwise set n = lVIglobal and continue.
