PS: Honestly I just proposed my first challenge on PPCG hours ago, so feel free to criticize me.
I just had my very first challenge published here and I ran into a problem that some answers are based on a slightly changed description of the challenge.
Two examples: 1, (in MMA post) The challenge says 0 for in and 1 for out; The first version of 30-byte long code changed it into -1 for in and 1 for out.
2, (in Octave post) The challenge requires input to be an array of triples (though it is the answerer's freedom to choose two of them, leading to different algorithm, and the freedom is discussed in the last part). The code left out one column, and made the input an array of double, or two arrays.
Should I remove restrictions and focus on core algorithms here? The removal will not break codes submitted and gives future code more freedom. If it is OK, to what extent am I able to change the description for I am really interested in golfing code. I may learn for the next challenge.
