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?

Mostafa on 26 Oct 2016

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

Aditya Jain on 26 Oct 2016

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

Jeff Connors on 30 Mar 2020

this cheapo solutions need to be deleted, no one benefits from this or learns about matlab

Steve Tasker on 13 Jun 2020

Alfonso, please remove this nonsense score which prevents those of us trying to learn from actually discovering how to improve our prgramming

源樹上林 on 13 Aug 2020

なるほどこんな解決策があるのか！全く参考にならない。

function y = times2(x)
y = x * 2;
end
