Struct TapeObjective 

pub struct TapeObjective<F: Float> { /* private fields */ }

Adapter wrapping a BytecodeTape as an Objective.

Implementations

impl<F: Float> TapeObjective<F>

pub fn new(tape: BytecodeTape<F>) -> Self

Create a new TapeObjective from a recorded tape.

pub fn func_evals(&self) -> usize

Number of function evaluations performed so far.

pub fn tape(&self) -> &BytecodeTape<F>

Borrow the underlying tape.
