Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
objective estimation » objective optimization, objective allocation
active learning » machine learning
mom algorithm » adam algorithm, mppt algorithm, _ algorithm
learning mom » learning from, learning model, learnings from

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: (( active learning mom algorithm ) OR ( modified objective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( active learning mom algorithm ) or ( modified objective estimation algorithms ))*.
