In the interactive environments, there must be used such an optimization
algorithm, running as fast as the refresh rate needs. That could be
a problem, because some optimization-based algorithms are quite ``dumber''. When such
algorithm is used, some problems could appear. For example,
the algorithm jams in the local minimum and is not able to find the
global solution. Some more sophisticated algorithms may be used, but
the time cost could be probably higher.
The good idea is the use of any minimization solver which could be
applied like plug-in module. It is easy to change the solver and it allows
usage of handy solver according to a specific situation. There are not
problems with matrix inversion as well.
