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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( based self learning algorithm ) OR ( modified parameter optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( based self learning algorithm ) or ( modified parameter optimization algorithm ))*.
