gtsam::Assignment< L > Class Template Reference

Detailed Description

template<class L>
class gtsam::Assignment< L >

An assignment from labels to value index (size_t).

Assigns to each label a value. Implemented as a simple map. A discrete factor takes an Assignment and returns a value.

template<class L>

template<typename Derived = Assignment<L>>

std::vector< Derived > gtsam::Assignment< L >::CartesianProduct ( const std::vector< std::pair< L, size_t > > & keys )

inlinestatic

Get Cartesian product consisting all possible configurations.

Parameters

vector

list of keys (label,cardinality) pairs.

Returns

vector list of all possible value assignments

This function returns a vector of Assignment values for all possible (Cartesian product) configurations of set of Keys which are nothing but (Label,cardinality) pairs. This function should NOT be called for more than a small number of variables and cardinalities. E.g. For 6 variables with each having cardinalities 4, we get 4096 possible configurations!!
