Perhaps you should try some spelling variations:
parameter optimisation » parameter optimization, parameter estimation
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
predation algorithm » predators algorithm, estimation algorithm
a predation » _ predation, a prediction, orca predation
modified a » modified _, modified df, modified adam

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: "(( modified a predation algorithm ) OR ( modified parameter optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified a predation algorithm ) OR ( modified parameter optimisation algorithm ))*.
