double faiss::RankingScore2::accum_gt_weight_diff	(	const std::vector< int > &	a,
		const std::vector< int > &	b
	)

inline

count nb of i, j in a x b st. i < j a and b should be sorted on input they are the ranks of j and k respectively. specific version for diff-of-rank weighting, cannot optimized with a cumulative table
