Class min_de_base (o2scl)

O2scl : Class List

template<class func_t, class dfunc_t = func_t>
class min_de_base : public o2scl::min_base<func_t, func_t>

One-dimensional minimization using derivatives [abstract base].

At the moment there are no minimizers of this type implemented in .

Idea for Future:

Create a version of o2scl::mmin_conf which implements a minimizer with this interface.

Public Functions

inline min_de_base()

inline virtual ~min_de_base()

virtual int min(double &x, double &fmin, func_t &func) = 0

Calculate the minimum min of func w.r.t ‘x’.

If this is not overloaded, it attempts to bracket the minimum using bracket() and then calls min_bkt() with the newly bracketed minimum.

virtual int min_bkt(double &x2, double x1, double x3, double &fmin, func_t &func) = 0

Calculate the minimum min of func with x2 bracketed between x1 and x3.

If this is not overloaded, it ignores the bracket and calls min().

virtual int min_de(double &x, double &fmin, func_t &func, dfunc_t &df) = 0

Calculate the minimum min of func with derivative dfunc w.r.t ‘x’.

If this is not overloaded, it attempts to bracket the minimum using bracket() and then calls min_bkt_de() with the newly bracketed minimum.

inline virtual const char *type()

Return string denoting type (“min_de”)
