Perhaps you should try some spelling variations:
objective optimization » multiobjective optimization
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
one algorithm » our algorithm, _ algorithm, mom algorithm
model using » code using, models nursing, powder using
using one » using open, using pre, using online

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