gtsam::AllDiff Class Reference
Detailed Description
General AllDiff constraint Returns 1 if values for all keys are different, 0 otherwise DiscreteFactors are all awkward in that they have to store two types of keys: for each variable we have a Key and an Key.
In this factor, we keep the Indices locally, and the Indices are stored in IndexFactor.
