In particular, genetic algorithms are designed to evolve, with various mechanisms being used to mimic natural selection. One such mechanism is to assign "costs" to various aspects of the program, and to select for programs which assess a {{w|fitness function}} such as calculating the least sum of all these costs (thus mimicking organisms in an environment where they have to compete for limited resources) versus any measurable benefits. | In particular, genetic algorithms are designed to evolve, with various mechanisms being used to mimic natural selection.

By setting an absurdly high cost for an algorithm transforming into Skynet, the coder makes a preventive measure against the algorithm achieving such sentience. |

The title text refers to the method by which the program select the desired option, with minimizing being where the program seeks the lowest possible number, and maximizing where the program seeks the highest possible number. When dealing with cases such as generating profit, maximization would obviously be preferred over minimization; but selecting maximization here would be disastrous as it would always chose the BecomingSkynet option before any other due to its massive cost. | The title text refers to the method by which the program select the desired option, with minimizing being where the program seeks the lowest possible number, and maximizing where the program seeks the highest possible number.
