Perhaps you should try some spelling variations:
multiobjective optimisation » multiobjective optimization, objective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
search algorithm » source algorithm
models using » model using, models nursing, code using
using search » using egarch, nursing research, using servo

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 multiobjective optimisation algorithm ) OR ( models using search algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified multiobjective optimisation algorithm ) OR ( models using search algorithm ))*.
