We have been trying to generate weighted graph for two popular graph frameworks, GAPBS and Ligra to generate graphs with weights one from SNAP format edge lists. Here are some our experiences.
To get GAPBS to add weights of 1 to your edgelist file
change the insertWeights to insert 1 instead of random numbers.
to generate, just use converter
./converter -f input.el -w -e weighted_input.wel
to generate a binary weighted graph
./converter -f weighted_input.wel -w -e weighted_input.wsg
To get Ligra to add weights of 1 to your edgelist file
change the adjGraphAddWeights
change the parallel_for that writes to Weights.
A tricky part here is you need to compile this file in the utils directory.
