ConicBundle::QPKKT_KKTStats Class Reference

Used for collecting statics in QPKKTSolverComparison: For each bundle subproblem there is a block QPKKT_ProbStats, which holds for each KKT system a block of QPKKT_KKTStats (this), which holds for each solver a block QPKKT_SolverStats. More...

Detailed Description

Used for collecting statics in QPKKTSolverComparison: For each bundle subproblem there is a block QPKKT_ProbStats, which holds for each KKT system a block of QPKKT_KKTStats (this), which holds for each solver a block QPKKT_SolverStats.

Member Function Documentation

add_col()

int ConicBundle::QPKKT_KKTStats::add_col ( CH_Matrix_Classes::Matrix &  prepsecs, CH_Matrix_Classes::Matrix &  predsecs, CH_Matrix_Classes::Matrix &  corrsecs, CH_Matrix_Classes::Indexmatrix &  predcalls, CH_Matrix_Classes::Indexmatrix &  corrcalls  )

inline

adds the respecitve values of the solvers to last column. It is used for collecting cummlative data for each subproblem per solver. Columns are subproblems, rows are solvers

Parameters

prepsecs	preparation time (one row for each solver)
predsecs	predictor time (one row for each solver)
corrsecs	corrector time (one row for each solver)
predcalls	predictor matrix vector multiplications (one row for each solver)
corrcalls	corrector matrix vector multiplications (one row for each solver)

append_col()

int ConicBundle::QPKKT_KKTStats::append_col ( CH_Matrix_Classes::Matrix &  muvals, CH_Matrix_Classes::Matrix &  prepsecs, CH_Matrix_Classes::Matrix &  predsecs, CH_Matrix_Classes::Matrix &  corrsecs, CH_Matrix_Classes::Indexmatrix &  predcalls, CH_Matrix_Classes::Indexmatrix &  corrcalls, CH_Matrix_Classes::Matrix &  cond, CH_Matrix_Classes::Indexmatrix &  pccols, CH_Matrix_Classes::Matrix &  sysviol  )

inline

appends the statsitics data of this KKT system as the last column of the repsective matrices

Parameters

muvals	the barrier parameter,
prepsecs	preparation time (one row for each solver)
predsecs	predictor time (one row for each solver)
corrsecs	corrector time (one row for each solver)
predcalls	predictor matrix vector multiplications (one row for each solver)
corrcalls	corrector matrix vector multiplications (one row for each solver)
cond	condition number estimate (one row for each solver)
pccols	rank of the predictor (one row for each solver)
sysviol	norm of the system residual for corrector (one row for each solver)
