Struct InfPrFloor 

pub struct InfPrFloor { /* private fields */ }

Running evidence, over one solve, that it found a floor on the constraint violation and could not get below it.

Fed once per outer iteration from the value already computed for the inf_pr column, so it costs no function evaluations. The restoration sub-IPM has its own InfPrFloor on its own IpoptData, measuring its own (restoration) NLP; the guard reads the outer one.

Implementations

impl InfPrFloor

pub fn observe(&mut self, inf_pr: Number)

Record the scaled primal infeasibility at one iterate.

pub fn iters_at_floor(&self) -> Index

How many iterates sat within an order of magnitude of the floor this solve settled at. 0 when nothing was observed.

pub fn floor(&self) -> Number

The violation the count is measured against, or INFINITY if nothing was observed. Diagnostic only.

pub fn samples(&self) -> Index

How many iterates were observed. Diagnostic only.
