Introduction

This is a brief documentation for using Irene. Irene was originally written to find reliable approximations for optimum value of an arbitrary optimization problem. It implements a modification of Lasserre’s SDP Relaxations based on generalized truncated moment problem to handle general optimization problems algebraically.

Requirements and dependencies

This is a python package, so clearly python is an obvious requirement. Irene relies on the following packages:

• for vector calculations:

  • NumPy.
  • SciPy.

• for symbolic computations:

  • SymPy.

• for semidefinite optimization, at least one of the following is required:

  • cvxopt,
  • dsdp,
  • sdpa,
  • csdp.
