# Competition
Predicts how person will do in competition
It is an example how `protected` can be useful in Ruby.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'competition'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install competition
## Usage
```ruby
require "competition"
```
### Creating Competition object
```ruby
person_a = Competition::Person.new(intelligence: 33, willpower: 20)
person_b = Competition::Person.new(intelligence: 47, willpower: 17)
person_c = Competition::Person.new(intelligence: 39, willpower: 25)
competition = Competition::Competition.new
competition << person_a
competition << person_b
competition << person_c
```
### Determining person predicted rating
```ruby
person_a.in_competition(competition).predicted_rating #=> 45.009699999999995
```
## How it works
```
rating = affected_intelligence + 0.5 * affected_willpower, where:
affected_intelligence = intelligence * (1.03 ** more_intelligent_opponent_count)
affected_willpower = willpower * (0.97 ** less_intelligent_opponent_count)
```
