Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
objective optimization » multiobjective optimization
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
modified network » certified network, defined network, modified near

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