Perhaps you should try some spelling variations:
"modified water optimization algorithms" » "modified water optimisation algorithm", "modified water estimation algorithms", "modified water estimation algorithm", "modified game optimization algorithms", "modified market optimization algorithms", "modified static optimization algorithms", "modified male optimization algorithms"
"modified delphi solution algorithm" » "modified delphi evolution algorithm", "modified delphi convolution algorithms", "modified delphi evolutionary algorithm"

Try widening your search to All Fields.

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

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