# Modeling Functions and Expressions

Functions, expressions, constraints.

- Is it possible to feed black-box functions to Gurobi?
- How do I access the left-hand side of a constraint?
- How do I model conditional statements in Gurobi?
- Why doesn't Gurobi support strict inequality constraints like x < a?
- How do I divide by a variable in Gurobi?
- How do I model multilinear terms in Gurobi?
- How do I model piecewise-linear functions?
- How do I model a piecewise-linear function of more than one variable?
- How do I model logical and general expressions?
