This would mean that either R matches and the candidate doesn't or R doesn't match while the candidate does. If the two regular expressions agree on all the test strings, select "equivalent". caa*[​rt​]s? [partA] ca+[​rt​]s* [partB] ca+(r|t)s? [partC] ca+[​rt​]?s? [partD] ca+rs? [partE] ca*[​rt​]s? [partF]
