Problem  Solved  by Chinese Mathematicians ?
but i could not find any comprehensive materials on web how they expained the solution ?
how they did use power of computer for finding proofs ?
 

thanks a lot Kitonum

it must be very useful for research on pixel based shapes

dear Alsu did you stop posting topics ?

I am proud to Hail Erik Postma

Kitonum thanks a lot

   I admire all  the Maple developers and their team work spirit !

To be a mathematician demand the creed of Pythagoras ... Einstein that made millennium. names for humanity !

Unlike the Stefan wolfram that prefered marketing rather than the Creed of a real Mathematician !

he assuming himself as a prophet like Moses and wrote huge book as Tora and all the rest of mankid must obey the only ten commandments he manage ...

JOHN MAY !

ARE YOU A SORCERER ?

@one man 
if i don't speak so foolish !
i guess your model can be extended so that it simulate a wheel that find its path in a weary road ?
somthing related to tires movment physics !

welcome and nice subject

thanks a lot !
it is so interesting for me !!!

Thanks a lot for your valuable solutions !

The collection of works you published here are prototypes for advanced facilities !

@Markiyan Hirnyk 

Sir i just found some animation like the one i showed but there was not mathematical definition for the animations ! So i can't understand what geometry they made of ?

My purpose is the formula for curvature?

I hope if i did something wrong or offtopic you awarn me on it ?

Many respects !

@Markiyan Hirnyk 

Sorry ! Now by two answers of MaplePrimes mathematicians i able to find the right way !

@Thomas Richard 
they are really wonderful structures !
your sincerely Shekofte

@acer 
indeed i am not a professional !
but i was so interested in concept of Gömböc shapes !
but thanks a lot for your help to disambiguate my question !
