Generates a problem environment for the XOR problem.

Description

Generates a problem environment for the XOR problem.

Usage

newEnvXOR()

Value

The problem environment for the XOR problem with

• $name: "envXOR", the name of the problem environment.

• $buildtest(expr): The function which builds the environment for evaluating the expression by binding the variables to the parameters.

• $TestCases: The truthtable of the XOR function.

• $f(expr, gene=NULL, lF=NULL): The fitness function. expr is the string with the logical expression to be evaluated.
