Finding free non-intersecting rectangle shaped areas between rectangles in C# -


I have the following problem: A large rectangle contains small non-intersecting rectangles (black rectangles in the picture below) and me To fill the remaining free area, there is a need to find an algorithm, which is with no piercing rectangles (red color in the picture below). There is no problem with speed algorithm. Also if I have an example source code for an algorithm, then I really appreciate it.

Edit Small explanations I need to get the coordinates of red rectangles do not attract them. I am not working with point data too.

Most bin-packing problems like this for me as a NP-hard problem Looks 2, with rectangles, there are 8! (= 40320) Possible arrangements you need to consider. Three rectangles produce 12! Possibilities, 480 million cool.

You will need to make an estimate to make this calculable. In favor of the outer edges of the rectangles near the boundary rectangular, I do not like the results you will need hard requirements on the resulting rectangles, many of them are not helping, it is not my problem :)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
