Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"modified deep evolution algorithm" » "modified deep solution algorithm", "modified deep evolutionary algorithm", "modified deep convolution algorithms", "modified delphi evolution algorithm", "modified df evolution algorithm", "modified near evolution algorithm"

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

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