I need to do a quadratic optimization problem in python where the

What are the possible choices to do this.

Too bad these homework assignments get trickier every time, isn't it?

I think this sarcasm is unjustified. It is not obvious to me that this

is a homework assignment.

The problem where constraints are linear and the objective function is

linear (quadratic) is known as linear (quadratic) programming, and

there are specialized codes for these problems. I don't know of

software in any language for the particular problem of a linear

objective function with quadratic constraints, so I would use a general

algorithm for nonlinearly constrained optimization. Maybe CVXOPT

http://www.ee.ucla.edu/~vandenbe/cvxopt/ will work for the OP -- I have

not tried it.

The site

http://www.solver.com/probconic.htm calls the problem "conic

optimization".

A good newsgroup to ask about optimization algorithms is

sci.math.num-analysis.
