# Performs a machine-coded genetic algorithm search for a given optimization problem

### Description

`mcga2`

is the improvement version of the standard mcga function as it is based on the `GA::ga`

function. The
`byte_crossover`

and the `byte_mutation`

operators are the main reproduction operators and these operators uses the byte
representations of parents in the computer memory.

### Usage

1 2 3 4 5 6 7 | ```
mcga2(fitness, ..., min, max,
population = gaControl("real-valued")$population,
selection = gaControl("real-valued")$selection,
crossover = byte_crossover, mutation = byte_mutation, popSize = 50,
pcrossover = 0.8, pmutation = 0.1, elitism = base::max(1, round(popSize
* 0.05)), maxiter = 100, run = maxiter, maxFitness = Inf,
names = NULL, parallel = FALSE, monitor = gaMonitor, seed = NULL)
``` |

### Arguments

`fitness` |
The goal function to be maximized |

`...` |
Additional arguments to be passed to the fitness function |

`min` |
Vector of lower bounds of variables |

`max` |
Vector of upper bounds of variables |

`population` |
Initial population. It is |

`selection` |
Selection operator. It is |

`crossover` |
Crossover operator. It is |

`mutation` |
Mutation operator. It is |

`popSize` |
Population size. It is 50 by default |

`pcrossover` |
Probability of crossover. It is 0.8 by default |

`pmutation` |
Probability of mutation. It is 0.1 by default |

`elitism` |
Number of elitist solutions. It is |

`maxiter` |
Maximum number of generations. It is 100 by default |

`run` |
The genetic search is stopped if the best solution has not any improvements in last |

`maxFitness` |
Upper bound of the fitness function. By default it is Inf |

`names` |
Vector of names of the variables. By default it is |

`parallel` |
If TRUE, fitness calculations are performed parallel. It is FALSE by default |

`monitor` |
The monitoring function for printing some information about the current state of the genetic search. It is |

`seed` |
The seed for random number generating. It is |

### Value

Returns an object of class `ga-class`
