Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
predation algorithm » predators algorithm, estimation algorithm
effective reading » effective gradient, active reading
reading predation » reading promotion
parameter » parameters

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( effective reading predation algorithm ) or ( modified parameter optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( effective reading predation algorithm ) OR ( modified parameter optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( effective reading predation algorithm ) or ( modified parameter optimization algorithm ))*.
