Options to speed up discrete minimization.
--X-rtd MINIMIZER_multiMin_hideConstants: hide the constant terms in the likelihood when recreating the minimizer--X-rtd MINIMIZER_multiMin_maskConstraints: hide the constraint terms during the discrete minimization process--X-rtd MINIMIZER_multiMin_maskChannels=<choice>mask in the NLL the channels that are not needed:<choice> 1: keeps unmasked all channels that are participating in the discrete minimization<choice> 2: keeps unmasked only the channel whose index is being scanned at the moment (works only in multipleMinimize mode 0, makes discrete minimization faster)All the options work only if
--X-rtd MINIMIZER_freezeDisassociatedParamsis enabled.It is possible that already setting maskChannels=2 and SIMNLL_GROUPCONSTRAINTS=N make the gain from hideConstant and maskConstraints redundant in practice but I haven't tested since I developed them in the order they're listed here.
