# V 0.2.0 | ||
- Allow ngen configuration to specify routing output file name to look for. | ||
- `Evaluatable` objects are now responsible for maintaining the `evaluation_parms` property, including `evaluation_range` | ||
- `evaluation_range` removed from `Meta` | ||
- `eval_params` bundeled and moved to model config from global, these include the following configuration keys | ||
- `evaluation_start` | ||
- `evaluation_stop` | ||
- `objective` | ||
- Add `bounds` property to `Adjustable` interface | ||
- Use an `Agent` abstraction to connect model runtime, calibration objects, and evaluation criteria | ||
- All model execution now happens in automatically generated subdirectory | ||
- Introduce PSO global best serach, only applicable for `uniform` stragegy | ||
- Allow additional search algorithm parameters to be configured by the user | ||
- For DDS, the configuration can supply the `neighborhood` parameter as follows, if not supplied, a default of 0.2 is used | ||
```yaml | ||
strategy: | ||
type: estimation | ||
algorithm: dds | ||
parameters: | ||
neighborhood: 0.5 | ||
``` | ||
- For PSO, the configuration can supply the following parameters | ||
```yaml | ||
strategy: | ||
type: estimation | ||
algorithm: "pso" | ||
parameters: | ||
pool: 4 #number of processors to use (by default, uses 1) | ||
particles: 8 #number of particles to use (by default, uses 4) | ||
options: #the PSO parameters (defaults to c1: 0.5, c2: 0.3, w:0.9) | ||
c1: 0.1 | ||
c2: 0.1 | ||
w: 0.42 | ||
``` | ||
- Restart semantics have changed slightly. Restart is only supported for DDS search, with the following caveats: | ||
If a user starts with an independent calibration strategy | ||
then restarts with a uniform strategy, this will "work" but probably shouldn't. | ||
it works cause the independent writes a param df for the nexus that uniform also uses, | ||
so data "exists" and it doesn't know its not conistent... | ||
Conversely, if you start with uniform then try independent, it will start back at | ||
0 correctly since not all basin params can be loaded. | ||
There are probably some similar issues with explicit and independent, since they have | ||
similar data semantics. | ||
- Fix issue with independent strategy not writing ngen forcing configs for target catchments in a way that ngen can handle. |
