Update of /cvsroot/quantproject/QuantProject/b7_Scripts/TickerSelectionTesting
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv20797/b7_Scripts/TickerSelectionTesting
Modified Files:
GenomeManagerForEfficientPortfolio.cs
Added Files:
MeaningForGenome.cs
Log Message:
Added MeaningForGenome class, to be used inside the TickerSelectionTesting namespace.
Decode implementation in GenomeManagerForEfficientPortfolio (and so the Meaning property for the correlated Genome) has been changed.
