python-algebraic provides a convenient and portable method for specifying linear and nonlinear constraints and objective functions. It is written for use with python-zibopt but can be used by other solver interfaces.

At the moment it only supports functionality necessary for SCIP, but more is one the way.

Quick Start:

from algebraic import variable

# Use variable as a mixin to your decision variable class
class MyVariableType(variable):
 pass

# You can now use expressions and variables with the same algebraic
# modeling syntax available to python-zibopt:
#
# (x + 1) * (x - 1) < = 2
# etc.
