# Creating advanced Models

This chapter is about advanced (Mixed) Integer Problems. For each problem a mathematical problem formulation is given and afterwards implemented.

Additionally an Implementation and Instantiation of the Business objects is provided.

If you want to get all the models at once and their respective interfaces please download from github.

## Prerequisites

Please look at Getting Started first for the most basic functions and the setup of OPTANO.Modeling

## Mixed Integer Linear Problems

**Exemplary implementations* of some of the most common Mixed Integer Problems:**

## Integer Problems

**Exemplary implementations* of some of the most common Integer Problems:**

The Knapsack Problem

The N-Queens Problem

Solving Sudoku

**Please note, that each implementation is highly reusable due to the usage of interfaces.*
