OptimizationState

OptimizationState(; iter=0, u=nothing, objective=nothing, grad=nothing,
    hess=nothing, original=nothing, p=nothing)

State passed to an optimization callback after a solver step.

Fields

• iter: current iteration.
• u: current optimization variables.
• objective: current objective value.
• grad: current gradient, when available.
• hess: current Hessian, when available.
• original: solver-specific state object, when available.
• p: current optimization parameters.

Examples

state = OptimizationState(; iter = 2, u = [1.0], objective = 0.5)
state.iter == 2
