HHC / HP Museum Programming Contest for RPN and RPL machines  Gene Wright  09212013 The RPN contest writeup: The RPL contest writeup:
Do not post any solutions to the forum until at least 6pm Sunday Denver (Mountain USA) time. Please be careful about **questions** you post here about the contest too. Some questions in the past have actually given away how to solve the problem. Keep your cards close to your chest.

Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Pier Aiello  09212013 Could i load these on wiki4hp ?
edit: for now i guess "yes", if it is the contrary, just tell me i'll remove the pdfs from wiki4hp. Edited: 21 Sept 2013, 11:36 a.m.
UPDATE RPL change ...Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gene Wright  09212013 No base 16 for the RPL contest. ONLY bases 2, 8 and 10 entered as real numbers.
Sorry about that.
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Pal G.  09212013 Gene, thanks for including those of us who could not make the trek. Thanks for doing it each year.
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gerson W. Barbosa  09212013 RPN, HP15C, 19 steps, first version: 0.5 R/S > 0.625 ( 2.4 s)Impossible to time, but it shouldn't take longer than 0.1 s on the HP15C LE. Gerson. P.S.: Rounding error in the last example (correct result: 0.999999994)

Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Egan Ford  09212013 Quote:My HP12C (circa 1981) RPN version is also 19 steps: 0.5 R/S > 0.625 ( 2.3 s)
Update: 18 steps. Edited: 21 Sept 2013, 5:37 p.m.
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gerson W. Barbosa  09212013 Thanks for sharing your results!

Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Egan Ford  09212013 Right now my 12C version only supports 0 <= x < 1. Rules state that 1 is included. So I may need a few more steps. 21 steps for 0 <= x <= 1.
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gerson W. Barbosa  09212013 Same here. I overread the part that says "Each test case will consist of a value in octal between 0 and 1, inclusive."
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gerson W. Barbosa  09212013 20 steps for 0 <= x <= 1. Costing me 3 extra steps as well.
Keep going all... FYI  I developed my version that runs on an HP 65  Gene Wright  09212013 39 steps, unfortunately for several reasons... unmerged steps bad programming
:)
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Mark Storkamp  09212013 RPN, HP41CX, 19 steps
0 R/S > 0 (0.39s)
Timing done with the internal stopwatch. (I didn't count those lines in the total number of steps) Edited: 22 Sept 2013, 7:22 a.m. after one or more responses were posted
Re: Keep going all... FYI  I developed my version that runs on an HP 65  Gerson W. Barbosa  09212013 Mostly due to lack of merged steps, of course!
Gerson.
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gerson W. Barbosa  09222013 Quote: 14 steps. Sounds great! Looking forward to seeing your solution (when the time is right, of course).
Just for fun: HP15C 32 steps, however. Gerson.

Re: UPDATE RPL change ...Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Eric Smith  09222013 There was another rules clarification at the conference that no base conversion functions can be used. I think that might eliminate a few of the shortest entries that have been described here, but of course I haven't seen them so I don't really know. My RPN entry is currently 19 steps on WP34S or HP42S, and probably the same for the 15C but I haven't thought about that much. I need two more steps on the HP41C. I'm too tired now to figure out how to time it.
148 bytes (not counting global name) for my RPL entry on the 50g. It was 153.5 bytes until I realized that one of my clever optimizations actually made it longer.
Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Olivier De Smet  09222013 HP41 : 7 steps with label and END :) (should be the same as Mark) Not timed but very quick :) Convert as 20 steps for an HP65 with label and RTN (some peculiarities adds 2 steps)

Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Miguel Toro  09222013 Hi, WP 34S, 19 steps without labels. Very fast but no actual times, though. Thank you for the challenge.

Same here, but I'm using wp34s specific instructions, so probably more on the 42s. I didn't even try the 12C or 33C (perhaps I'd need 5 or 6 more instructions on those).
Re: UPDATE RPL change ...Re: HHC / HP Museum Programming Contest for RPN and RPL machines  Gerson W. Barbosa  09222013 Update: I decided to use only the stack. As a result, 18 steps now. Perhaps more saving is possible, but I have to leave.
