dwave.optimization.model.Symbol.maybe_equals#
- Symbol.maybe_equals(other)#
Compare to another node.
This method exists because a complete equality test can be expensive.
- Parameters:
other – Another node in the model’s directed acyclic graph.
- Returns: integer
Supported return values are:
0
—Not equal (with certainty)1
—Might be equal (no guarantees); a complete equality test is necessary2
—Are equal (with certainty)
Examples
