try to see if lambda is the ratio from budget so ive removed it from initialize and placed it where lambda is in the article.
didnt work.
Add new library to work with graphs, the rgl.
Fixed article example. Fix the implementation to follow the article. In the article it presume that the graph is already transitive to do so i implemented the transitive closure and used it in the place of the original graph. And change graphviz for rgl.
