maxClique {RBGL}R Documentation

Find all the cliques in a graph

Description

Find all the cliques in a graph

Usage

maxClique(g)

Arguments

g

an instance of the graph class

Details

Notice the maximum clique problem is NP-complete, which means it cannot be solved by any known polynomial algorithm.

We implemented the algorithm by C. Bron and J. Kerbosch,

Value

maxClique

list of all cliques in g

Examples

con1 <- file(system.file("XML/conn.gxl",package="RBGL"), open="r")
coex <- fromGXL(con1)
close(con1)

maxClique(coex)

con2 <- file(system.file("XML/hcs.gxl",package="RBGL"), open="r")
coex <- fromGXL(con2)
close(con2)

maxClique(coex)
