It discusses object identity, type constructors, encapsulation, type hierarchies, inheritance, polymorphism, and operator overloading.
The considered object-oriented features which have mutation operator implemented are: Inheritance, Polymorphism and Overloading, with 8, 7 and 3 mutation operators per feature, respectively.
The major way to the inheritance of parents is the crossover operator, the operation of which occurs for a selected pair with a crossover rate.
Finally, the forth mutation operator is ISD, from Inheritance category.
Classes are partial message definitions that can be combined and transformed by means of operators for behavioral and synchronization inheritance.
During the evolutionary optimization process, each new generation was created by using several genetic operators, including the best solution inheritance, roulette wheel selection, one-point crossover, random mutation, and gene modification.
We chose the "AND" operator in order to create a multiple inheritance (e.g. Mallory-Weiss syndrome will be both in "Laceration related disorders" as well as in "Haemorrhage related disorders").
The inheritance of the Rh system probably depends on the existence of operator genes, which turn the activity of closely linked structural genes on or off.
Object inheritance An LTL expression is represented as a top-level LTL operator, which in turn may contain a number of children operators, hence creating a nested structure representing the contents of the formula.
6 The inter-class mutation operators for Java [59] pose a similar challenge: mutations of inheritance and polymorphism elements also require broad analyses of the compiled application.
