Error; running a new routing algorithm. #38

Closed setat closed 6 years ago

setat commented 6 years ago

Hi, I want to try a new routing algorithm; I've changed XY routing (in order not to get error of power) and I ran the command below: ./noxim -config ../config_examples/default_config.yaml

and got this error:

From the last message, it seems that your code does not provide a set of possible directions. You get different messages because there is probably something that depends on random seed. First of all, try to use -seed option to repeat the same scenario. Then enable verbose logs (see slide 36 of https://github.com/davidepatti/noxim/blob/master/doc/noxim_tutorial.pdf)
