The method string used in rave::Factory has the following general structure:

finder-name:value-name:value-...

Sometimes nesting is required (e.g. to configure "sub-algorithms"):

finder-name:value-name:(value-name:value-name:value)....

As for the finders, the following algorithms are defined:

kalman

    KalmanVertexFitter This is the simple linear kalman filter that takes no extra parameters. 
avf

    AdaptiveVertexFitter The avf respects the following parameters:

    sigmacut

        The value for [ = sqrt (2) ] at which a track has track weight=0.5. 
    Tini

        Initial temperature in the annealing schedule. 
    ratio

        The ratio with which the temperature falls in each iteration step. 

    Default is: avf-Tini:256-ratio:0.25-sigmacut:3 
tkf

    TrimmedKalmanVertexFinder The tkf respects the following parameters:

    ptcut

        Cut in the tracks' pT, given in GeV/c. 
    vtxcut

        Bla FIXME 
    trackcutpv

        Bla FIXME 
    trackcutsv

        Bla FIXME 

    Default is: tkf-ptcut:0-trkcutpv:0.05-trkcutsv:0.01-vtxcut:0.01
