Visual Models of Morphogenesis (Przemyslaw Prusinkiewicz et al.)
Grow more plants with algorithm
- a population of 1000; [think about local maximum- could be a problem for sparse samples across the set]
- some evaluation to score each individual/ fitness function.s
- kill the ones underscore certain threshold;
- the survivor breed offspring. HOW?
- the likely hood of mutation M, say 3%
- crossover C, 5%
- parametric representation of the individuals.

- repopulate the died portion

Outline of the Basic Genetic Algorithm
1.[Start] Generate random population of n chromosomes
2.[Fitness] Evaluate the fitness of each chromosome
3.[New population] Create a new population by repeating:
A.[Selection] Select two parent chromosomes based on their fitness
B.[Crossover] With a crossover probability cross over the parents to
form new offspring (children). If no crossover was performed,
offspring is an exact copy of parents.
C.[Mutation] With a mutation probability mutate new offspring at
each locus (position in chromosome).
D.[Accepting] Place new offspring in a new population
4.[Replace] Use new generated population for a further run of algorithm
5.[Test] If the end condition is satisfied, stop, and return the best
solution in current population
6.[Loop] Go to step 2

- Evolving Morphology with Control , i.e. body and brain
- Evolution at times involves more than competition with the environment
