add_edges/4¶

add_edges(+ Graph, + Edges, - NewGraph)*

Unify NewGraph with a new graph obtained by adding the list of edges Edges to the graph Graph. In the next example:

 ?- add_edges([1-[3,5],2-[4],3-[],4-[5],5-[],6-[],
 7-[],8-[]],[1-6,2-3,3-2,5-7,3-2,4-5],NL).

 NL = [1-[3,5,6],2-[3,4],3-[2],4-[5],5-[7],6-[],7-[],8-[]]
