gramEvol: Grammatical Evolution in R

We describe an R package which implements grammatical evolution (GE) for automatic program generation. By performing an unconstrained optimisation over a population of R expressions generated via a user-defined grammar, programs which achieve a desired goal can be discovered. The package facilitates the coding and execution of GE programs, and supports parallel execution. In addition, three app...

Policy Evolution with Grammatical Evolution

Security policies are becoming more sophisticated. Operational forces will often be faced with making tricky risk decisions and policies must be flexible enough to allow appropriate actions to be facilitated. Access requests are no longer simple subject access object matters. There is often a great deal of context to be taken into account. Most security work is couched in terms of risk manageme...

Grammatical Differential Evolution

This proof of concept study examines the possibility of specifying the construction of programs using Differential Evolution, and represents a new form of grammar-based genetic programming, Grammatical Differential Evolution (GDE). In GDE each individual member of the population represents a specific choice of program construction rules, where these rules are specified using a Backus-Naur Form ...

Constituent Grammatical Evolution

We present Constituent Grammatical Evolution (CGE), a new evolutionary automatic programming algorithm that extends the standard Grammatical Evolution algorithm by incorporating the concepts of constituent genes and conditional behaviour-switching. CGE builds from elementary and more complex building blocks a control program which dictates the behaviour of an agent and it is applicable to the c...
