/**
 * @param fvs Input FeatureVectorSequence
 * @param gammas Marginals over single states
 * @param xis Marginals over pairs of states
 * @param transducer Transducer
 * @param reverseTrans Source state indices for each destination state
 * @param reverseTransIndices Transition indices for each destination state
 * @param gradient Gradient to increment
 * @param constraints List of constraints
 * @param check Whether to run the debugging test to verify correctness (will be much slower if true)
