This paper presents a comparison of a graph-based genetic algorithm (GB-GA) and machine {learning|studying|understanding|finding out|mastering} (ML) {results|outcomes|final results|benefits} for the optimisation of logP values {with a|having a|using a} constraint for synthetic accessibility and shows that GA is as {good|great|excellent|very good|fantastic|superior} or {better|much better|far better|greater|superior|improved} than the ML approaches for this {particular|specific|certain|distinct|unique} {property|home|house}. The molecules {found|discovered|identified|located} by GB-GA bear {little|small|tiny} resemblance {to the|towards the|for the} molecules {used|utilized|employed|utilised|applied|made use of} to construct the initial mating pool, indicating that the GB-GA {approach|method|strategy} can traverse a {relatively|fairly|comparatively|reasonably|somewhat} {large|big|huge|massive|substantial|significant} distance in chemical space {using|utilizing|making use of|employing|working with|applying} {relatively|fairly|comparatively|reasonably|somewhat} {few|couple of|handful of} (50) generations. The paper also introduces {a new|a brand new} non-ML graph-based generative model (GB-GM) {that can be|that may be} parameterized {using|utilizing|making use of|employing|working with|applying} {very|extremely|really|quite|incredibly|pretty} {small|little|tiny|modest|smaller|compact} {data|information} sets and combined {with a|having a|using a} Monte Carlo tree search (MCTS) algorithm. {The results|The outcomes} are comparable to previously published {results|outcomes|final results|benefits} (Sci.
