`#include <CGAL/Surface_mesh_simplification/Policies/Edge_collapse/Count_ratio_stop_predicate.h>`

## Definition

The class `Count_ratio_stop_predicate` is a model for the `StopPredicate` concept which returns `true` when the relation between the initial and current number of edges drops below a certain ratio.

Template Parameters

  ECM | is the type of surface mesh being simplified, and must be a model of the `EdgeCollapsableSurfaceMesh` concept.

Is Model Of:
  `StopPredicate`

  `CGAL::Surface_mesh_simplification::Count_stop_predicate<ECM>`

## Creation

| Count_ratio_stop_predicate (double ratio)
| Initializes the predicate establishing the `ratio`.

## Operations

bool | operator() (FT const &current_cost, Profile const &edge_profile, size_type initial_count, size_type current_count) const
| Returns `( ((double)current_count / (double)initial_count) < ratio)`. More...

## Member Function Documentation

template<typename ECM >

bool CGAL::Surface_mesh_simplification::Count_ratio_stop_predicate< ECM >::operator() | ( | FT const & | current_cost,
|  | Profile const & | edge_profile,
|  | size_type | initial_count,
|  | size_type | current_count
| ) |  | const

Returns `( ((double)current_count / (double)initial_count) < ratio)`.

All other parameters are ignored (but exist since this is a generic policy).
