Further specifications of refined covariate\nbalance restriction and exact match on covariate can be\nimposed. Matches are approximately optimal in the sense that\nthe cost of the solution is at most twice the optimal cost,\nCrama and Spieksma (1992) <doi:10.1016/0377-2217(92)90078-N>,\nKarmakar, Small and Rosenbaum (2019)\n<doi:10.1080/10618600.2019.1584900>.",
