Introduce `BeliefPropagationProblem` wrapper to hold the cache and the error `diff` field. Also simplifies some kwargs wrangling.
…be set from another cache
Also includes some fixes to the way `TensorNetwork` types are constructed based on index structure.
for more information, see https://pre-commit.ci
…instead of trying to operate on existing graphs The reason for this is: - One only cares about the edges of the input graph - A simple graph cannot be used as it "forgets" its edge names resulting in recursion - As shown with `TensorNetwork`, removing edges may not always be defined.
…s from an array.
This was caused by the change to the `cache` being backed by a directed graph.
This method was just forwarding the underlying graph.
An `AbstractTensorNetwork` has edge type `Nothing`, which can be obtained from the `AbstractDataGraph` method.
…type; other small changes.
… the `stopping_criterion` kwarg.
