Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified adaptive evolution algorithm" » "modified adaptive solution algorithm", "modified adaptive evolutionary algorithm", "modified adaptive convolution algorithms", "modified adaptive ventilation algorithm", "modified passive evolution algorithm"

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 algorithms\") OR (\"modified adaptive evolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified adaptive evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified adaptive evolution algorithm"))*.
