Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
real algorithm » adam algorithm, search algorithm
model using » code using, models nursing, powder using
using real » using metal, using raw

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 objective optimisation algorithm ) OR ( model using real algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimisation algorithm ) OR ( model using real algorithm ))*.
