Perhaps you should try some spelling variations:
parameters optimization » parameter optimization, parameter estimation
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
tracking algorithm » learning algorithm
self tracking » self teaching, self training, speck tracking
based self » based gel, based sers, based semi

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( based self tracking algorithm ) OR ( modified parameters optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( based self tracking algorithm ) OR ( modified parameters optimization algorithm ))*.
