Packomania's wizard

Suppose, you have to pack a bundle of circles of different diameters into a larger container circle.
How the circles must be sized and arranged in order to achieve a packing density as high as possible?

Please use the following form for this calculation:

Input diameters/radii
Please specify the number and the size of each set of congruent circles at one line.
Separate number and size by white spaces (blanks or tabs).
size may be either a diameter or a radius, don't mix diameters and radii here.

You want to pack one circle of diameter 0.056", nine circles of diameter 0.120" and two circles of diameter 0.256",
then input these data as:
1   0.056
9   0.120
2   0.256
Execution time
30   60   120   300Please select the execution time (in seconds).
Seed for random number generator
Give here the seed for the random number generator. Normally, this seed is generated automatically, so that repeated calls of the wizard with the same input data produce different results. But if you like to get the same result as in an earlier run then input the appropriate seed.
If you leave this input field blank then the seed will be generated automatically.
