Detailed Description
This class is a work node computation hook (- See also:
- work_node_comp_hook), which calculates lower and upper bounds on the objective function on the work node and keeps them in the columns ``obj lowbound'' and ``obj upbound''. The diameter of the interval is kept in the column ``obj diameter''

| bool coco::objbounds_comp_hook::drop_columns | ( | vdbl::standard_table & | stable | ) | [inline, virtual] |
Upon unregistering this hook, destroy the columns ``obj lowbound'' ``obj diameter'', and ``obj upbound'' in the ``search info'' table.
Reimplemented from coco::wnc_hook_base.

| bool coco::objbounds_comp_hook::init_columns | ( | vdbl::standard_table & | stable | ) | [inline, virtual] |
Upon registering this hook, initialize the columns ``obj lowbound'' ``obj diameter'', and ``obj upbound'' in the ``search info'' table.
Reimplemented from coco::wnc_hook_base.
Definition at line 120 of file objbounds_hook.h.
| const std::string& coco::wnc_hook_base::name | ( | ) | const [inline, inherited] |
Return the identifier string of this work node computation hook.

The evaluation operator of this computation hook. It stores the lower and upper bounds on the objective function on the work_node wn in dbt_row dbr.
Implements coco::wnc_hook_base.
