All matches are compared against the record-set in the next iteration. Therefore, the number of record-pairs increase exponentially as new matches are found. This means fewer record-pairs (memory usage) but a longer run time compared to the "no" option. Conversely, it leads to more record-pairs (memory usage) but a shorter run time compared to the "yes" option.batched) in episodes()

Create permutations of record-sets.links() - When shrink is TRUE, records in a record-group must meet every listed match criteria and sub_criteria. For example, if pid_cri is 3, then the record must have meet matched another on the the first three match criteria.links() - pid@iteration now tracks when a record was dealt with instead of when it was assigned to a record-group. For example, a record can be closed (matched or not matched) at iteration 1 but assigned to a record-group at iteration 5.make_pairs() - x.* and y.* values in the output are now swapped.sub_criteria can now export any data created by match_func. To do this, match_func must export a list, where the first element is a logical object. See an example below.
