## Definition

template<typename TriangleMesh>
class CGAL::Surface_mesh_simplification::LindstromTurk_cost< TriangleMesh >

The class `LindstromTurk_cost` provides a model for the `GetCost` concept.

It computes the collapse cost following the Lindstrom-Turk strategy (Section Lindstrom-Turk Cost and Placement Strategy)

Template Parameters

  TriangleMesh | is the type of surface mesh being simplified, and must be a model of the `MutableFaceGraph` and `HalfedgeListGraph` concepts.

Is model of
  `GetCost`

## Creation
| LindstromTurk_cost (const FT factor=FT(0.5))
| Initializes the policy with the given weighting unit factor.

## Operations
std::optional< typename Edge_profile::FT > | operator() (const Edge_profile &edge_profile, const std::optional< typename Edge_profile::Point > &placement) const
| Returns the cost of collapsing the edge (represented by its profile) considering the new `placement` computed for it.
