We have developed an algorithm that can produce reasonable solutions to the Escherization problem. It is based on three large components:

Python module offering solvers for Constraint Solving Problems (CSPs) over finite domains in simple and pure Python.

Math and Python hack.

A time determinant logarithmic progression, with a movable target and energy factor.

Nice.

Repeating a calculation or simulation over a range. with input parameters varied over tolerance ranges

Always useful.

Rotating objects with complex numbers.

Python interface to ePiX.

Python bindings for proj4.

Module for Python, adding NaN, Infinite, etc.

Generators and the rationals.

Some nice functions.

Python and primes.

Spline interpolation in Python.

...with Python!

Interface to SPHEREPACK3.

RSOAP provides a SOAP interface for the Open-Source statistical package R.

Using R from Python.

a system for doing mathematics with Python
