Added functions setLogFileNameCPLEX and getLogFileName for interfacing CPLEX functions CPXsetlogfilename and
CPXgetlogfilename if building package with CPLEX Version >= 12.8.0.
Added funtion getParmHierNameCPLEX for interfacing CPLEX funtion CPXgetparamhiername if building with CPLEX Version 12.9.0.
Interface Functions openFileCPLEX, closeFileCPLEX, addFpDestCPLEX, delFpDestCPLEX, fileputCPLEX,
setLogFileCPLEX, and getLogFileCPLEX will have no functionality and return NULL, if building with CPLEX version >= 12.9.0,
because related CPLEX functions CPXfopen, CPXfclose, CPXaddfpdest, CPXdelfpdest, CPXfputs, CPXsetlogfile,
and CPXgetlogfile had been removed in CPLEX Version >= 12.9.0. For using logfiles, use setLogFileNameCPLEX and getLogFileName
instead.
maintainer change
The function solution should avoid returning the dual solution if solved FIXEDMILP, MILP, QCP, MIQCP, MIQP, and FIXEDMIQP.
In CPLEX Version 1270 are the functions CPXaddchannel and
CPXdelchannel removed (http://www.ibm.com/support/knowledgecenter/SSSA5P_12.7.0/ilog.odms.cplex.help/CPLEX/ReleaseNotes/topics/releasenotes127/removed.html).
Fixed a bug in getQuad(). Thx to Florian Schwendinger.
Added function getNumQConstrsCPLEX to access cplex function
CPXgetnumqconstrs
added support for new parameter names introduced in IBM ILOG CPLEX version 12.6
fixed a bug in function addQConstrCPLEX()
added functions getQConstrCPLEX(), delQConstrsCPLEX(),
addIndConstrCPLEX(), getIndConstrCPLEX() and
delIndConstrsCPLEX()
added function addQConstrCPLEX()
added functions copyOrderCPLEX(), getOrderCPLEX(),
readCopyOrderCPLEX and ordWriteCPLEX
bugfix in function getMIPrelGapCPLEX()
added function getMIPrelGapCPLEX()
does not print the version number of IBM ILOG CPLEX on startup, because of problems with IBM ILOG CPLEX versions less than 12.5
added support for IBM ILOG CPLEX version 12.5
minor update in file ‘configure.ac’ to be compatible with IBM ILOG CPLEX version 12.5
minor change in file ‘src/Makevars.win’
prints the version number of IBM ILOG CPLEX on startup

added getMIPstartsCPLEX to ‘NAMESPACE’
added function getBestObjValCPLEX()
renamed cplexPtr method isNULLpointer to
isNULLpointerCPLEX
renamed cplexPtr method pType to cplexPtrType
renamed cplexPtr method ptr to cplexPointer
renamed cplexPtr slot pType to cplexPtrType
renamed cplexPtr slot ptr to cplexPointer
updated ‘configure.ac’ script, see ‘INSTALL’ for updated installation instructions
updated ‘configure.ac’ script: all printf commands in
‘check.c’ will be replaced trough Rprintf during configure
file ‘NEWS’ is now in ‘inst/NEWS.Rd’
function ‘getMIPstartsCPLEX()’ is not exported, it is not working properly
added functions refineConflictExtCPLEX(),
getConflictExtCPLEX(),
refineMIPstartConflictCPLEX(),
refineMIPstartConflictExtCPLEX(),
getNumQPnzCPLEX(),
getNumQuadCPLEX(),
getQPcoefCPLEX(),
getQuadCPLEX() and
chgQPcoefCPLEX().
exported API-functions are registered
added finalizers for pointers to IBM ILOG CPLEX environments
Functions like openEnvCPLEX() and initProbCPLEX() return
now instances of class cplexPtr. This class has two slots:
| pType | a character string giving the pointer type and |
| ptr | a pointer to a C structure |
updated package vignette
C function status_message() now uses REprintf instead of
fprintf to printing to stderr
C function printTerminate() uses Rprintf instead of printf
added methods isNULLpointer, isCPLEXprobPointer,
isCPLEXenvPointer, isCPLEXfilePointer,
isCPLEXchanPointer and isCPLEXtermPointer for objects
of class cplexPtr
method show for objects of class cplexPtr
method summary for objects of class cplexPtr
method show for objects of class cplexError
added functions addMIPstartsCPLEX(),
chgMIPstartsCPLEX(),
getMIPstartsCPLEX(),
getNumMIPstartsCPLEX(),
delMIPstartsCPLEX(),
writeMIPstartsCPLEX(),
readCopyMIPstartsCPLEX(),
getMIPstartNameCPLEX() and
getMIPstartIndexCPLEX().
added support for IBM ILOG CPLEX version 12.4
added -Wl,-no_compact_unwind to ‘configure.ac’ for
MacOS X amd64
S3 class cpxerr is now S4 class cplexError
added functions checkCopyQuadCPLEX(),
copyQuadCPLEX() and
qpoptCPLEX()
minor update in ‘configure.ac’
updated documentation
added compatibility to IBM ILOG CPLEX version 12.3: new functions
getInfoLongParmCPLEX(), getLongParmCPLEX() and
setLongParmCPLEX()
removed argument ncols from getLowBndsIdsCPLEX() and
getUppBndsIdsCPLEX()
getStatStrCPLEX() needs argument env, it can not be
NULL
getParmTypeCPLEX() returns instance of class cpxerr when
failed
updated documentation
avoid changing parameters by assignment
some changes in S3 class cpxerr, new methods:
as.cpxerr | default constructor |
errmsg | get error message |
errnum | get error number |
err | cat error message |
'errnum<-' | set/change error number |
