 # Introduction
 This jupyter-book provides python implementation for various concepts and algorithms related to **Surrogate Methods**. The jupyter-book has been created by the **Computational Design (CODE) Laboratory** led by **Prof. Leifur Leifsson** at **Purdue University**. This jupyter-book is intended to be used as a starting point for new users of surrogate methods to implement the concepts and algorithms for their own work. The creation of this jupyter-book is funded partly by the National Science Foundation (NSF) award number 2223732.
