Quadratic Programming with Python and CVXOPT

Quadratic Programming with Python and CVXOPTThis guide assumes that you have already installed the NumPy and CVXOPT packagesfor your Python distribution. You can check if they are installed by importing them:import numpyimport cvxoptLet us first review the standard form of a QP (following CVXOPT notation):minx12x>P x+q>xsubject toGx hAx=bNote thatx>denotes the transpose ofx, andGx hmeans that the inequality is takenelement-wise over the vectorsGxandh. The above objective function is convex if and onlyifPis positive-semidefinite, which is the realm we are concerned CVXOPT QP framework expects a problem of the above form, defined by the pa-rameters{P, q, G, h, A, b};Pandqare required, the others are optional.

Basic Plotting with Python and Matplotlib

courses.csail.mit.edu

The basic syntax for creating line plots is plt.plot(x,y), where x and y are arrays of the same length that specify the (x;y) pairs that form the line. For example, let’s plot the cosine function from 2 to 1.

In case Pand Qare complex-valued, in which case we call Pdx+Qdya complex 1-form, we again de ne the line integral by integrating the real and imaginary parts separately. Next we recall the basics of line integrals in the plane: 1.
