# Large scale evolutionary optimization using cooperative coevolution

## Notes

### CC (cooperative coevolution)

- steps:
- problem decomposition;
- subcomponent optimization;
- subcomponent coadaptation;

- citations: 6, 10, 11, 15, 16, 25;

### DE (differential evolution)

- description, cited 1, 13, 18;
- benchmarks, cited 23;
- parameters, cited 3, 13, 28;
- adaptations, cited 20;
- operators:
- crossover:
- we must ensure that at least one element is changed (they select a random index and ensure that it is used in crossover);

- crossover:

### NSDE (differential evolution with neighbourhood search)

- description, cited 17;

### SaNSDE (self-adaptive NSDE)

- description, cited 26;
- benchmarks, cited 19;

### EACC-G

for each cycle a new subcomponent permutation is chosen;

*the grouping structure changes dynamically*;the subcomponent weights are still applied;

*adaptive weighting for coadaptation among subcomponents after each cycle*;- definition of separable and non-separable problems cited from 19;

### DECC-G

- combination between EACC-G and SaNSDE;

### DECC-O

the same as DECC-G, but with = 1;

### DECC-G-NW

- the same as DECC-G, but without weights;

### Benchmark

- functions, cited 19, 27;
- competitors FEPCC (cited 6), DECC-O (cited 15);
- parameters:
: 100;

: 100;

- cycles: 50;
