Thanks, I'll try this way and post any advances,

Thank you Matterwave I started like that, using element size as rule. I reduced all possible locations of the element a) as 2 (border and middle): XaXX aXXX XaXX aXXX XaXX aXXX XaXX aXXX These by 4 possible rotations, and by 2 possible mirror-like turns...

Nobody...? any similar problem? or an idea on what method to use for tackling it? a book? Anything would help

Hello, Yes, I need to count all the possible ways to fit them together, counting different rotations of the same configuration as different solutions. A way to illustrate it it is as a...

Hi Matterwave, Thank you for asking The rules are: all elements need to be in the solution, without overlapping and covering the whole area of the grid. This is 1 x a, 1 x b, 3 x c, and 3 x d. Like in Tetris, all the pieces need to come together with no empty spaces between them. Also they...

Hello All, I'm programming an applet and run over a problem I can't solve (hope this is the right place to post it): Having a 4 by 4 2d grid and 8 lineal elements: a) 1 of 4 square, b) 1 of 3 squares, c) 3 of 2 squares, and d) 3 of 1 suare: _grid: XXXX XXXX XXXX XXXX _elements: a) XXXX b) XXX...

Thanks... I need some caffeine.

Hi, I'm making a small app in java and part of the script retrieves an 'evaluation' factor from 'a' between -1 to 1 (e.g. 0.882) where 1 is the best and -1 is the worst. Now, my problem in that I need to change it into a positive factor form 'b' from 0 to 1 to compute with other factors. For...

Hi All, Just wanted to know, what is a good way to learn mathematical modeling? I'm a social scientist working with simulation and data, and would like approach the issue more formally. Before trying modeling textbooks, what should I know beyond calculus? Any suggestions (books, tutorials...

Great, thank you.

What does this mean? (see attachment) "Where b is a block defined by the contiguity condition c that may exist between elements of s, and n is the number of elements in that block" I know is not possible to get a solution without the actual function, but how does this reads?
