Is it a problem when two edges of this node have the same j?

See original GitHub issue

If I understand it correctly, in this snippet, when all the in_node in node point from the same node j, they will share the same node_str. When forward it will repeat the same operation and sum the results. It can be a problem.

      for in_node in node:
        name, j = in_node[0], in_node[1]
        node_str = '{:}<-{:}'.format(i+2, j)
        op = self.edges[ node_str ]
        clist.append( op(states[j]) )

That is a very good point, and I agree with that. The genotype function follows the original DARTS implementation. I will add a NOTE at here to clarify the mismatch between search and re-train.

@pomonam I feel it is case-by-case and should be determined by yourself. Both are fine and can be supported by some reasons.
