I have a small simulation that creates a network of agents who then play a game on the network. I noticed that when I run the simulation under R 3.1.3 igraph 0.7.1 it takes about 4 seconds. When I run it using R 3.5.1 with igraph 1.2.2 it takes about 4 minutes.
I use igraph to create a network and then extract neighbourhoods. The neighbourhoods are what is actually used to get the nodes to play the game. I re-wrote it to remove igraph from the code — to test whether igraph is the issue, I created a list directly which represented the neighbourhoods. With that elimination of igraph (and no other changes) it takes about 4 seconds under R 3.5.1 Some of the maintainers on the R list looked and came tot he same conclusion. The problem is with igraph changes between 0,7 and 1.2. Has this come to light before?
