# How to create an algorithm

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

## Overview

An algorithm is a schematic drawing that helps organizing step by step approaches in a visually simplified way. An algorithm is formed by a set of boxes and lines that join them.

## Create an Algorithm

### Introduction

• To begin an algorithm, you should start with the following code {{family tree/start}} and end it with {{family tree/end}}.
• You can name an algorithm by starting with following: {{family tree/summary= Name of the algorithm}}
• The algorithm consists of boxes that occupy virtual rows:
 Box 1 in Row 1 Box 2 in Row 2 Box 3 in Row 3 Box 4 in Row 3

• Each row is represented by the following where each | | represents a space.:

{{Family tree | | | | | | | | | }}

• Each box is represented by the content that fills the space in | |, for example | A01 | will give:
 A01
• In order to link the boxes you need to use symbols. The basic symbols that you will most commonly use are the following:
• ! will link two boxes placed vertically on top of each other
• - will link two boxes placed horizontally next to each other
• ^ will link bifurcate a line arising from a box into two branches.

### Algorithm Basics

You type:
```{{Family tree/start}}{{Family tree | | | | A01 |-| A02 | |A01= Box 1 in Row 1| A02= Box in Row 1}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box in Row 1
You type:
```{{Family tree/start}}{{Family tree | | | | A01 |-|-|-| A02 | |A01= Box 1 in Row 1| A02= Box in Row 1}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box in Row 1
You type:
```{{Family tree/start}}{{Family tree | | | | A01 |~| A02 | |A01= Box 1 in Row 1| A02= Box in Row 1}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box in Row 1
You type:
```{{Family tree/start}}{{Family tree | | | | A01 |~|~|~| A02 | |A01= Box 1 in Row 1| A02= Box in Row 1}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box in Row 1
You type:
```{{Family tree/start}}{{Family tree | | | | A01 | | | |A01= Box 1 in Row 1}}{{Family tree | | | | |!| | | | | }}{{Family tree | | | | B01 | | | |B01= Box 2 in Row 2}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box 2 in Row 2
You type:
```{{Family tree/start}}{{Family tree | | | | A01 | | | |A01= Box 1 in Row 1}}{{Family tree | | | | |!| | | | | }}{{Family tree | | | | |!| | | | | }}{{Family tree | | | | |!| | | | | }}{{Family tree | | | | B01 | | | |B01= Box 2 in Row 2}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box 2 in Row 2
You type:
```{{Family tree/start}}{{Family tree | | | | A01 | | | |A01= Box 1 in Row 1}}{{Family tree | | | | |:| | | | | }}{{Family tree | | | | B01 | | | |B01= Box 2 in Row 2}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box 2 in Row 2
You type:
```{{Family tree/start}}{{Family tree | | | | A01 | | | |A01= Box 1 in Row 1}}{{Family tree | | | | |:| | | | | }}{{Family tree | | | | |:| | | | | }}{{Family tree | | | | |:| | | | | }}{{Family tree | | | | B01 | | | |B01= Box 2 in Row 2}}{{Family tree/end}}
```
You get:
 Box 1 in Row 1 Box 2 in Row 2
