julia
set_risk_constraints!(
    model::Model,
    ,
    r::UlcerIndex,
    opt::RiskJuMPOptimisationEstimator,
    pr::AbstractPriorResult,
    args...;
    kwargs...
) -> Any

Add Ulcer Index risk constraints to model.

Introduces a scalar variable uci and the SOC constraint [sc * uci; sc * dd[2:T+1]] in SecondOrderCone(), then defines uci_risk = uci / sqrt(T). Returns the existing expression if already present.

Arguments

  • model::JuMP.Model: The JuMP optimisation model.

  • r::UlcerIndex: Ulcer index risk measure instance.

  • opt::RiskJuMPOptimisationEstimator: Risk-based optimisation estimator.

  • pr::AbstractPriorResult: Prior result containing the returns matrix X.

Returns

  • nothing.
