Methods for getting and setting optimized attributes | |
Optimizers don't have to go through the particles themselves looking for values to optimize unless they care about special properties of the optimized values. Instead they can iterate through the list of optimized attributes, each of which is identified by a FloatIndex. With these FloatIndex objects they can get and set the values and derivatives as needed. | |
| FloatIndexes | get_optimized_attributes () const |
| void | set_value (FloatIndex fi, double v) const |
| Float | get_value (FloatIndex fi) const |
| Float | get_derivative (FloatIndex fi) const |
Methods to get and set scaled optimizable values | |
Certain optimizers benefit from having all the optimized values scaled to vary over a similar range. These accessors use the Model::get_range ranges to scale the values before returning them and unscale them before setting them. | |
| void | set_scaled_value (FloatIndex fi, Float v) const |
| double | get_scaled_value (FloatIndex fi) const |
| double | get_scaled_derivative (FloatIndex fi) const |
| void | clear_range_cache () |
| Clear the cache of range information. Do this at the start of. | |
AttributeOptimizers optimize the collection of optimized attributes (see Model::set_is_optimized()) in contrast to, say molecular dynamics where the fundamental entity is a Particle.
