CS 5970 Homework 6 — Neuroevolution
for Problem Solving
Due Monday, November 9, 2015
Just as with evolutionary computation in general, to use neuroevolution
to solve problems, we need to apply them to particular problems. To do
that, we need to take the same actions with regard the evolutionary
computation aspects of neuroevolution as we do for any other application of
evolutionary computation (following De Jong, Evolutionary Computation: A
Unified Approach, p 72):
In addition, we need to make several decisions regarding what features of
our artificial neural networks (ANNs) will be evolved, such as connection
weights or various aspects of the structure of the network.
- decide what an individual in the population represents,
- provide a means for computing the fitness of an individual,
- decide how children (new search points) are generated from parents
(current search points),
- specify population sizes and dynamics,
- define termination criteria for stopping the evolutionary process,
- return an answer
The goals of this assignment are:
- to give you experience with reading papers from the primary,
peer-reviewed literature in evolutionary computation, and
- to give you experience with dissecting such papers and understanding
how evolutionary computation models are implemented for particular
- List and explain at least 10 distinct features of an ANN that could be evolved using neuroevolution.
Read the paper "Evolution of Robot-to-Robot Nurturing and Nurturability" by Leonce, Hoke, and Hougen and answer the questions below.
- What does an individual in the population represent?
- Is this a fixed-length linear object, a fixed-length nonlinear
object, a variable-length linear object, or a nonlinear variable-length
- How is each individual encoded?
- Is this encoding genotypical or phenotypical?
- How is fitness calculated for each individual in the population?
- What reproductive operators are used?
- What parameters are used for each of the reproductive operators?
- What is the parent population size?
- What is the offspring population size?
- Is an overlapping or non-overlapping generation model used?
- What stopping criteria are used?
- What answers are returned?
