Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms", "modified objective optimization algorithm", "modified multiobjective optimization algorithm"
"modified df evolution algorithms" » "modified df evolution algorithm", "modified df convolution algorithms", "modified df solution algorithm", "modified _ evolution algorithms", "modified co evolution algorithms", "modified adam evolution algorithms", "modified bi1 evolution algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified df evolution algorithms") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df evolution algorithms") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified df evolution algorithms ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified df evolution algorithms") or ("modified objective optimisation algorithm"))*.
