Quote by Mark Uniacke from Now Walking, 1982-1983: HIARCS 5 [6]:

The inspiration for the new HIARCS search was sought from the book Chess Skill in Man and Machine and in particular the article "The heuristic search: An alternative to the alpha-beta minimax procedure" by Larry Harris from Dartmouth College [7]. HIARCS was still written in the relatively primitive BASIC programming language and being interpreted it meant the program was rather slow. To compensate for this I developed some heuristics to help guide the search and evaluation in a more targeted way.
