Core function in computing consensus ranking as defined by Emond and Mason (2002), recalled by EMCons function
BBconsensus2(RR, cij, Po, PS = TRUE, FULL = FALSE)
A ranking
combined input matrix
current penalty
If PS=true, it prints the evaluating branches
Default FULL=FALSE. If FULL=TRUE, the searching is limited to the space of complete rankings. FULL=TRUE if the function is called by BBFULL algorithm.
