Webb15 aug. 2001 · The current atomic potential tends to pick lower RMSD structures than do residue-based contact potentials. In particular, this atomic pairwise interaction potential has better selectivity especially for near-native structures. Webb17 nov. 2024 · All-pairs testing, also known as pairwise testing, is a software quality assurance technique that involves a combination of expected input and output values. With this approach, software testers base their evaluation on paired sets of all possible parameters involved in testing a function.
