Re: Erreur

Hello,

There are several things you can try to increase the available memory :

1. Increase the maximum heap size of JVM, for example to have 1GB of heap, use
java -Xmx1G ...
or if you use IDE such as Eclipse, select Run > Run configurations,
then click the Arguments tab and in the box "VM arguments" add
"-Xmx1G"

2. If you are using SingleGraph or MultiGraph, try using
AdjacencyListGraph. This implementation is a bit slower, but consumes
less memory.

3. Don't use a viewer, it also takes memory. Try to compute
BetweennessCentrality before displaying the graph.

Hope it helps,
