#102 fixed Add lognormal distribution to Random. Balazs Dezso Alpar Juttner

The changeset [5e1b90e430c2] in the attachment is a lognormal distribution implementation. Please review it. I would also be happy with any feedback on the interface.

#4 fixed Add missing query functions to the LP interface Balazs Dezso Alpar Juttner

Functions required to retrieve

  • a row ( row(Row) )
  • a column ( col(Col) )
  • an element of the matrix ( coeff(Row, Col) )
  • the objective function ( obj(), objCoeff(Col) )
  • the row/col bounds ( colLowerBound(Col), colUpperBound(Col), rowLowerBound(Row), rowUpperBound(Row) )
  • etc

This ticket is a copy of report #14 of the old bug tracking system. It refers to svn trunk -r2470.

#91 fixed Add section reader to the LGF tools Balazs Dezso Alpar Juttner

Here comes two proposed interface for the reader (we might want to implement booth):

  • sectionStream(std::string name,F f). Here the parameter name is the section name (the word after @), while f is an unary functor, with an std::istream& parameter. When the reader finds a section that matches with name, then it calls f with an istream pointing to right after the section header line. f is required to recognize the end of the section and not to read further. Finally, f should return the number of read lines.
  • sectionLines(std::string name,F f). Here f takes an std::string as argument, an it will simply be called with each line of the matching section.

It would be important to have a section reader in LEMON 1.0, as it is necessary to port glemon.
