pub const UNEXPLOITED_HINTS: &[&str];Expand description
Options that are honored in the sense that matters — the answer is unaffected — but whose performance hint pounce does not exploit. These warn rather than fail: refusing them would stop a solve that returns the right result today, only a little slower.
Empty since gh #588 phase Q6. The four constant-derivative hints
(grad_f_constant, hessian_constant, jac_c_constant,
jac_d_constant) lived here and are now exploited:
pounce_nlp::constant_derivatives reconciles each one against what
the model can prove about its own algebra, and
OrigIpoptNlp reuses the derivative across iterates when the answer
is yes. A hint the model disproves still produces a warning — but a
louder one, from that module, saying the hint was refused rather than
merely unused.
The table stays because the shape is right for the next hint that
arrives registered-but-unexploited, and because
hint_warnings and its two membership tests are the mechanism that
keeps such an option from going silent again.
