What the heck is freepass?

Ramesh Vukyam on 23 Oct 2013

Is this a solution ?

Nice place to test... ;-)

cute but ridiculous

why it's 'freepass.please',not other words else?

Alfonso Nieto-Castanon on 28 Jun 2014

'freepass' is just a (cute but ridiculous) hack (see problem http://www.mathworks.com/matlabcentral/cody/problems/1774-free-passes-for-everyone ). The 'please' part is because we are really polite...

hello Alfonso !
I'd like to know how the solution size for your solution to the 'times two' question is '0'

can you please explain ?
thanks !

Erenca on 29 Oct 2015

how is this even possible, solution with 0 size?

Dan Po on 24 Sep 2016

does freepass; still work?

"Leading Solution is 0".. Just.. How?!

I rescored this solution and it failed

Alfonso Nieto-Castanon on 26 Oct 2016

@Aditya: I do not appreciate this solution being rescored, this particular solution had historical value to me, but obviously not to you

Aditya Jain on 26 Oct 2016

The reason I rescored your solution is because a solution cannot have a size of 0. With respect to your comment on the historical value, I think the solution is still there and I haven't changed that. If you still believe its an error from my side, you can email ned.gulley@mathworks.com and we can discuss it further.

Aditya Jain on 26 Oct 2016

Another solution is that you could use your free pass trick and rescore this solution again. I just don't want the solution to have a size of 0.

Alfonso Nieto-Castanon on 26 Oct 2016

Zero-score solutions have some history in Cody (see problem 42396). This solution was the only zero-score freepass solution (all other passing freepass solutions got a score of 100 for good reasons), so having this solution now fail the test removes its score and hence its significance. In any way, this is all fine and just a game, I just think it would be sad to see all of the other solutions in Cody that got zero, negative, maxint or other "impossible" scores being rescored for no good reason (#endofgetoffmylawnrant)

Aditya Jain on 26 Oct 2016

Good Point. I speak to Ned about this and discuss whether we should keep such solutions or not.
Thanks for the input and sorry for the trouble. #peace

Aditya Jain on 26 Oct 2016

@Alfonso: I have reverted back my change :)

Alfonso Nieto-Castanon on 27 Oct 2016

that's fantastic, thanks!

Tried the freepass command on my computer, all I get is
Undefined variable "freepass" or class "freepass.please".
Also I have no idea how code size is calculated
