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)
