Detailed Description

Solver-native solution metadata produced by the Gurobi backend.

When an OptSolution is produced by a Gurobi solve, OptSolution::external_results points to an instance of this class so the caller can read Gurobi-specific status, node counts, gap, and dual bound. Inspect via dynamic_cast / isinstance.

Member Function Documentation

◆ clone()

std::shared_ptr< ExternalSolverResults > ZonoOpt::GurobiSolverResults::clone ( ) const

inlineoverridevirtual

Polymorphic copy; required so callers can deep-copy an OptSolution.

Implements ZonoOpt::ExternalSolverResults.

◆ print()

std::string ZonoOpt::GurobiSolverResults::print ( ) const

inlineoverridevirtual

Human-readable summary of the solver-specific fields.

Reimplemented from ZonoOpt::ExternalSolverResults.

Member Data Documentation

◆ iter_count

double ZonoOpt::GurobiSolverResults::iter_count = 0.0

Simplex / barrier iteration count (Gurobi attribute "IterCount").

◆ mip_gap

double ZonoOpt::GurobiSolverResults::mip_gap = 0.0

Relative MIP optimality gap achieved at termination (Gurobi attribute "MIPGap").

◆ node_count

double ZonoOpt::GurobiSolverResults::node_count = 0.0

Number of branch-and-bound nodes explored (Gurobi attribute "NodeCount").
