Presentation Transcript

  1. ECJ • Overview • Suggested Plan • Access and setup • Tutorials and examples • Eclipse • FYI

  2. Overview • Java based • Very powerful • LaTeX option for fancy trees • Some reading and experimentation is necessary

  3. Suggested Plan • Download • Decide on a development environment • Eclipse • Text editor • Your favorite IDE • Introduction • Read ECJ Homepage • Briefly read parameter files • Look at Tutorial 1 at least • Tutorial 4 and examples • Closely follow 4 • Perform some examples • Create your own simple example • Begin work on your final project

  4. Access and setup • Download from http://www.cs.umd.edu/projects/plus/ec/ecj/ • Get the documentation from http://www.cs.umd.edu/projects/plus/ec/ecj/docs/ • Delete the package “teambots” unless you want to do more research about it

  5. Tutorials and examples • You should read through Tutorial 1 and Tutorial 4 at least. • You must not skip Tutorial 4 • Read slowly as this is the very core of understanding the classes used to represent the individuals you will evolve • There are over 20 different GP examples • Artificial ant, Boolean multiplexer, lawn-mowers, even-odd parity, etc. • Understand the details of the simple examples before you move on

  6. Eclipse • Just a suggestion – don’t use this unless you feel like you want to invest the time in getting a very nice IDE • Download from www.eclipse.org • Import from file system, make sure you filter just the *.java

  7. FYI • ECJ does not class-distinguish between functions and terminals . Rather, terminals are just 0-arity functions. • Parameter files can seem very complicated – they are really just an inheritance model implemented across a set of text files – but this can be confusing when you first look through it. Read through the “about parameter files” and trace through the ones used for a simple example.
