## WHAT IS IT?

Esta es una simulación basada en el  [artículo](https://link.springer.com/chapter/10.1007%2F978-3-642-32066-8_10). La simulación pretende evaluar las diferentes variables que se toman en cuenta en una evacuación o salida de un lugar.

## HOW IT WORKS

 La simulación toma en cuenta la distancia a las salidas, la densidad de personas cercanas a la salidas, la fragancia(esto no es es más que la relación de personas que 
escogen una salida u otra, mientras más personas escogen una salida mayor fragancia tiene esta) y tambien se tiene otra variable que es el ancho como tal de una salida, en esta simulación las salidas tienen la misma dimensión pero se puede simular el valor de esto aumentando o disminuyendo el valor **throughput-left** o **throughput-right**.
