RE: HHC 2018 Programming Contests
The announcement at HHC 2018 that the winner of the HP41 RPN Programming Contest was Kerry Veenstra was prefaced by these comments:
"The winning RPN entry was considered 'most elegant' for several reasons. First of all, it used no trig to calculate the Extrema Dates, but instead used Number Theory to jump over nonExtrema Dates. This is not only a clever approach, but it also made the program fun to use, because unlike other approaches, it found the answer for any input very quickly. For example, the HP 50g programs which were submitted took an entire minute to find the answer for an input of 18 May 1975, but this HP41 program finds the same answer in just 9 seconds! It was also accompanied by a thorough and clearly written program description giving program usage instructions, details of how it works, and an inlinecommented listing, all typed up and elegantly printed." Kerry's submission, scanned into a PDF file, can be found here: http://hhuc.us/2018/contest/Veenstra.pdf More contest entries will be uploaded as time permits. <0ɸ0> Joe
