Only works for fully connected graphs

[jivjen]

Was trying to run the acopy solver for fully connected graphs and it works fine but throws a key error whenever the graph is not fully connected.

Hi @rhgrant10 ,

I tried to use the custom class IncompleteGraphSolver from #21 and got the error:
NameError: name 'i' is not defined.

Then I change the iteration to properly get an ant from ants and got another error:
...line 231, in optimize
data.sort()
TypeError: '<' not supported between instances of 'Ant' and 'Ant'

I tried some more and changed the optimizer to not use the sort method and got another error:
line 274, in global_update
if edge in solution.path:
AttributeError: 'Ant' object has no attribute 'path'

Can you please point any direction? What am I missing here?
I really need acopy to work on an incomplete graph.

Thanks in advance
