To explain human performance on the "Traveling Salesperson" problem (TSP), MacGregor, Ormerod, and Chronicle (2000) proposed that humans construct solutions according to the steps described by their convex-hull algorithm. Focusing on tour length as the dependent variable, and using only random or semirandom point sets, the authors…

Chronicle, Edward; MacGregor, James; Ormerod, Thomas – Journal of Problem Solving, 2006
The two-dimensional Traveling Salesperson Problem (TSP) requires finding the shortest tour through n locations. Untrained adults are adept at the task and reliably outperform simple construction algorithms for n= 60. Performance may stem from a specific inherent ability. Alternatively, it may reflect general spatial intelligence, whether inherent…
