Hello everybody,

I am working on a geometry problem. On a drawing sheed I have various

lines it. I am trying to find the free space around the lines i.e,

dodge the lines. I am working in a prolog environment. If any body

has faced a similar problem pls. contact me and if you have a solution

to it even better. This is slightly similar to linear programming,

but linear programming only gives me the vertices (basis) of the free

space and I do not want maximize or minimize anything only find free

space.

Another problem I will be facing soon is is arraning a series of boxes

(quadrilateral ) on sheets of paper. The boxes are sometimes related

to each other in a simple fashion. The bottom line is to arrange the

boxes such that they dont clash and at the same time economizing for

space thus fewer sheets of paper.

thanks, in advance.

suresh.
