Show Slide: Title Slide	Hello and welcome to the Spoken Tutorial on “Installation of FOSSEE Optimization Toolbox in Scilab”.
Show Slide: Learning Objectives	In this tutorial, we will learn how to: Install the FOSSEE Optimization Toolbox. Execute a few examples using the toolbox.
Show Slide: System Requirements	To record this tutorial, I am using Ubuntu 18.04 as the operating system and Scilab 6.1.0
Show Slide: Installation Requirements	For the installation- We require a working Internet connection.
Show Slide: Pre-requisite	Before practising this tutorial, a learner should have : Basic knowledge of Scilab and Optimization Theory. For Scilab, please refer to the Scilab tutorials available on the Spoken Tutorial website.
Show Slide: What is FOSSEE Optimization Toolbox?	What is FOSSEE Optimization Toolbox? FOT is a toolbox in Scilab. It solves optimization problems using functions like linprog, fmincon and many others. It can solve Linear Programming, Mixed-Integer Linear Programming, Quadratic Programming, Nonlinear Programming, minimax, goal-attain, least squares and Minimization/maximization with or without constraints problems.
	There are several ways to install the toolbox. I will demonstrate one of the ways.
Scilab console>> type atomsGui >> press Enter	Open Scilab. In the Scilab console, type atomsGui and press Enter.
Module Manager- ATOMS window Point to Categories list on the left.	This will open the Module Manager- ATOMS window. You will see a Categories list on the left side.
Click once on the Optimization category	Click once on the Optimization category.

Point to help contents on this toolbox on the right	This will open the Help contents on this toolbox on the right hand side.
Click on the fot_fmincon function.	Click on the fot_fmincon function. This function is used to solve a general nonlinear optimization problem.
Scroll down Point to the first example. Click on the Execute button	Scroll down until you reach the Examples section. Let us execute the first example. Scroll to the right until you see the Execute button on the first example. Click on the Execute button.
Switch to the Scilab console.	Switch to the Scilab console. You can see that the example got executed successfully. Some of the values displayed on my console may differ from what you get. You can safely ignore this. Now let us execute one more example.
Switch to the Help window Click on fot_linprog	Switch to the Help window. On the left hand side, scroll down and click on fot_linprog
Scroll down Click on the Execute button	On the right hand side, scroll down until you reach the Examples section. Let us execute the first example. Scroll to the right if needed, until you see the Execute button on the first example. Click on the Execute button.
