Multivariate optimisation of signal efficiency for given background efficiency, applying rectangular minimum and maximum requirements.

Also implemented is a "decorrelate/diagonalized cuts approach", which improves over the uncorrelated cuts approach by transforming linearly the input variables into a diagonal space, using the square-root of the covariance matrix.

Other optimisation criteria, such as maximising the signal significance- squared, \( \frac{S^2}{(S+B)} \), with S and B being the signal and background yields, correspond to a particular point in the optimised background rejection versus signal efficiency curve. This working point requires the knowledge of the expected yields, which is not the case in general. Note also that for rare signals, Poissonian statistics should be used, which modifies the significance criterion.

The rectangular cut of a volume in the variable space is performed using a binary tree to sort the training events. This provides a significant reduction in computing time (up to several orders of magnitudes, depending on the complexity of the problem at hand).

Technically, optimisation is achieved in TMVA by two methods:

Monte Carlo generation using uniform priors for the lower cut value, and the cut width, thrown within the variable ranges.
A Genetic Algorithm (GA) searches for the optimal ("fittest") cut sample. The GA is configurable by many external settings through the option string. For difficult cases (such as many variables), some tuning may be necessary to achieve satisfying results

Attempts to use Minuit fits (Simplex ot Migrad) instead have not shown superior results, and often failed due to convergence at local minima.

The tests we have performed so far showed that in generic applications, the GA is superior to MC sampling, and hence GA is the default method. It is worthwhile trying both anyway.
