Perhaps you should try some spelling variations:
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"
"modified deep solution algorithm" » "modified deep evolution algorithm", "modified deep convolution algorithms", "modified deep evolutionary algorithm", "modified delphi solution algorithm", "modified df solution algorithm", "modified near solution algorithm", "modified drug solution 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 objective estimation algorithm") OR ("modified deep solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective estimation algorithm ) or ( modified deep solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective estimation algorithm") or ("modified deep solution algorithm"))*.
