Dear All We are happy to inform you that SparsePOP 2.99 is released. <-- Changes in SparsePOP 2.99 --> (1) SparsePOP can be compiled by mex on Windows 7 with Visual Stadio 2010. (2) Some elements of the structure `SDPinfo' returned from SDPrelaxation.m and SDPrelaxationMex.m are changed: [Add] SDPinfo.SeDuMiA: the coefficient matrix A in the SDP with the SeDuMi format SDPinfo.SeDuMib: the coefficient vector b in the SDP with the SeDuMi format SDPinfo.SeDuMic: the objective vector c in the SDP with the SeDuMi format SDPinfo.SeDuMiK: the cone K in the SDP with the SeDuMi format SDPinfo.objeConstant: trans.objVonstant SDPinfo.objValScale: trans.objValScale SDPinfo.Amat: trans.Amat SDPinfo.bVect: trans.bVect [Delete] SDPinfo.K, SDPinfo.A, SDPinfo.b, SDPinfo.c, SDPinfo.K.f, SDPinfo.J. (3) We checked that SparsePOP can be compiled under a Windows machine with Microsoft Visual C++ 7.0 or later. (4) The previous version of readGMS.m recognized the expression `+ - 0.5' as 0.5, not -0.5. We fixed this bug. The current version read it as `-0.5'. In addition, we changed the number of digit for vpa. (5) symamd in SDPrelaxationMex.m returns a segmentation fault for a POP with unused variables. We fixed this bug. Best regards, Hayato Waki |

Dear All We are happy to inform you that SparsePOPC++ 2.59 and its Windows binary. SparsePOPC++ Windows binary works on Windows 7 without compiling and consists of source files of SparePOPC++ 2.59. <-- Changes in SparsePOPC++ 2.59 --> * Add a reference of METIS in README.txt * Some unsed variables in conversion.cpp, mysdp.cpp, etc. are eliminated.

Dear All We are happy to inform you that SparsePOP 2.98 is released. <-- Changes in SparsePOP 2.98 --> (1) Fixed a bug in readGMS.m. The previous version could not read the monomials which are located after the keyword ``objvar". (2) Fixed a bug in deleteVar.m. The previous version might substitute some fixed values incorrectly for POPs whose lower and upper bounds are identical. (3) Some functions for scaling POPs with polynomial sdp constraints do not work in the current version. (4) SparsePOP with param.mex=1 returns the same format as param.mex=0 when users set param.detailedInfFile. |

Dear All We are happy to inform you that SparsePOP 2.97 is released. <-- Changes in SparsePOP 2.97 --> (1) Fixed a bug in substituteEq.m. (2) Improved output of information on SDPNAL in solveBySDPNAL.m and SDPT3 in solveBySDPT3.m. Best regards Hayato Waki |

Dear All We are happy to inform you that SparsePOP 2.96 is released. <-- Changes in SparsePOP 2.96 --> (1) Fixed bugs in compileSparsePOP.m and gen_basisindecies in conversion.cpp. (2) Improved the part of checking the linear independency of the coefficient matrix A. Best regards Hayato Waki |

Dear All
We are happy to inform you that SparsePOP 2.95 is released.
<-- Changes in SparsePOP 2.95 -->
(1) For POPs which have constraints "x in {0,1}" and/or
"x in {-1, 1}", SparsePOP can reduce the size of the
resulting SDP relaxation problem by exploiting their
constraints. This reduction is based on the following paper:
J.B.Lasserre, "An explicit equivalent positive semidefinite
program for nonlinear 0-1 programs", SIAM J.Optim., 12,
pp. 756--769.
* For the reduction for a POP which has constraint "x in {0, 1}",
set param.binarySW = 1.
* For the reduction for a POP which has constraint "x in {-1, +1}",
set param.SquareOneSW = 1.
However, these reductions do not work when user computes error
bounds of an approximated solution obtained by SparsePOP.
(2) The reductions executed by reduceMomentMatSW = 1 and/or
reduceAMatSW = 1 work when user computes error bounds of an
approximated solution obtained by SparsePOP.
(3) We move "class pop_params" from conversion.h into Parameters.h.
(4) Some bugs are fixed.
Best regards
Hayato Waki

Dear All We are happy to inform you that SparsePOP 2.90 is released. <-- Changes in SparsePOP 2.90 --> (1) SparsePOP can read the reserved keyword "maximizing objvar" and "binary variables". (2) Some gams files in GLOBAL Library are added in the directory example/GMSformat. (3) In the case where some variables in SDP relaxation problem corresponding to variables in a given POP are removed by setting param.reduceMomentMatSW = 1, SparsePOP returns only the optimal value of the resulting SDP relaxation problem. (4) Some bugs are fixed. Best regards Hayato Waki The University of Electro-Communications |

Dear All We are happy to inform you that SparsePOP 2.85 is released. <-- Change in SparsePOP 2.85 --> (1) Some bugs in C++ files of SparsePOP 2.80 are fixed. SparsePOP 2.85 can handle POPs which contain polynomial matrix inequalities by setting param.mex = 1. Best regards Hayato Waki The University of Electro-Communications |

Dear All We released C++ version of SparsePOP. This version has the following features: [1] This is based on SparsePOP 2.50. [2] This version uses SDPA 7.3.1 or later to solve SDP relaxation problems. [3] METIS and COLAMD are required to apply sparse SDP relaxation. [4] Users can install this version by "configure" and "make" into Linux and Mac OSX. This version is contained in the subdirectory "SparsePOPC++" of SparsePOP. See readme.txt in the subdirectory for installation, usage and details of this SparsePOP. Best regards Hayato Waki The University of Electro-Communications |

Dear All We start to release SparsePOP at SourceForge. The latest version is SparsePOP2.80. In this version, (i) users can use SeDuMi, SDPA, SDPT3, CSDP and SDPNAL for solving SDP relaxation prboelms, and (ii) we fixed some small bugs in SparsePOP 2.60.
