| int | max_model_size |
| maximum number of minorants to be selected for the cutting model (numbers<=1 for no limit, numbers >=2 impose a strict limit) | |
| int | max_bundle_size |
| suggested maximum number of latest minorants stored for use in a model, for constructing variable metric information etc. (negative numbers give no preference; the size may be increased internally in case of confliciting requirements, eg. in n_model_size or by variable metric routines) | |
| int | update_rule |
| in case several update rules are available | |
Detailed Description
Bundle parameters for SOCModel.
The current bundle update routine implemented in SOCModel may be controlled to some extent by passing SOCBundleParameters, but the update is well tuned already and the parameters are used in a quite different meaning than for the usual polyhedral model,so it seems better not to meddle with them.
The old parameters inherited from BundleParameters have the following meaning.
BundleParameters::max_model_size gives an upper bound on the subspace dimension, which is at least three here
BundleParameters::max_bundle_size gives an upper bound on the number of second order cone vectors that may stored for selecting the subspace
