Perhaps you should try some spelling variations:
objective optimization » multiobjective optimization
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
pre algorithm » mppt algorithm, qspr algorithm, _ algorithm
models using » model using, models nursing, code using
using pre » nursing pre, using one, using ph

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