Inheritance diagram for o2scl::min_de_base< func_t, dfunc_t >:
Detailed Description
template<class func_t, class dfunc_t = func_t>
class o2scl::min_de_base< func_t, dfunc_t >
At the moment there are no minimizers of this type implemented in O2scl .
- Idea for Future:
- Create a version of o2scl::mmin_conf which implements a minimizer with this interface.

Member Function Documentation
◆ min()
template<class func_t , class dfunc_t = func_t>
|
pure virtual |
If this is not overloaded, it attempts to bracket the minimum using bracket() and then calls min_bkt() with the newly bracketed minimum.
Implements o2scl::min_base< func_t, func_t >.
◆ min_bkt()
template<class func_t , class dfunc_t = func_t>
|
pure virtual |
If this is not overloaded, it ignores the bracket and calls min().
Implements o2scl::min_base< func_t, func_t >.
◆ min_de()
template<class func_t , class dfunc_t = func_t>
|
pure virtual |
If this is not overloaded, it attempts to bracket the minimum using bracket() and then calls min_bkt_de() with the newly bracketed minimum.
