NegativeRootCost Struct Reference

Public Member Functions
double	operator() (const Key< 3 > &key, const FunctionNode< double, 3 > &) const

Static Public Attributes
static constexpr double	root_cost = -1.e-3

Detailed Description

A negative cost at the root stands in for roundoff in its residual. The real residual can only go below zero after all children split off, which needs a large fac in load_balance().
