Definition of an optimisation problem

The definition of an optimisation problem involves:

  • the gradient of the cost function
  • the cost function
  • the set of constraints, which is described by implementations of Constraint

Implementations

Source

impl<'a, GradientType, ConstraintType, CostType, T> Problem<'a, GradientType, ConstraintType, CostType, T>
where GradientType: Fn(&[T], &mut [T]) -> FunctionCallResult, CostType: Fn(&[T], &mut T) -> FunctionCallResult, ConstraintType: Constraint<T>,

Source

pub fn new( constraints: &'a ConstraintType, cost_gradient: GradientType, cost: CostType, ) -> Problem<'a, GradientType, ConstraintType, CostType, T>

Construct a new instance of an optimisation problem

Arguments
  • constraints constraints
  • cost_gradient gradient of the cost function
  • cost cost function
Returns

New instance of Problem
