node14 A SIMD Interpreter for Genetic Programming on Graphics Cards
Protein Prediction - Mega Population
- 1213 proteins used for training
[Complex Systems, 15(4):285-306, 2005]
Randomly selected 200 at each fitness evaluation
- Spatial population 1024x1024 1,048,576 individual programs
- 1000 generation. 6 hours 46 mins
- Count of each of the twenty amino acids in the protein
and + - * /
- Programs of 63
- Tree depth limited to 8.
- Binary tournament selection
- 50% Subtree crossover and subtree mutation 5%,
22.5% point mutation, 22.5% constant adjustment mutation.
- Both selection and crossover act between neighbours.
- On holdout data the evolved program is
- significantly better than previous result
with one type of crossover and
- same performance but significantly smaller than that produced by
standard crossover
