TlpCholmod

Backend

CHOLMOD backend for solving linear systems.

See CholmodSolver for further details.

CholmodSolver{T,S<:AbstractKKTSystem}

CHOLMOD-based KKT solver.

Supported arithmetics

• Float64

Supported systems

• K2 via $LDLᵀ$ factorization
• K1 via Cholesky ($LLᵀ$) factorization

Examples

• To solve the augmented system with CHOLMOD's $LDL^{T}$ factorization:

set_parameter(tlp_model, "KKT_Backend", Tulip.KKT.TlpCholmod.Backend())
set_parameter(tlp_model, "KKT_System", Tulip.KKT.K2())

• To solve the normal equations system with CHOLMOD's Cholesky factorization:

set_parameter(tlp_model, "KKT_Backend", Tulip.KKT.TlpCholmod.Backend())
set_parameter(tlp_model, "KKT_System", Tulip.KKT.K1())
