Perhaps you should try some spelling variations:
"modified passive solution algorithms" » "modified passive evolution algorithm", "modified passive convolution algorithms", "modified passive estimation algorithms", "modified passive evolution algorithms", "modified passive convolution algorithmss", "modified passive evolutionary algorithms", "modified adaptive solution algorithms", "modified positive solutions algorithms", "modified saline solution 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 passive solution algorithms") or ("modified delphi solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive solution algorithms") OR ("modified delphi solution algorithm")).
• Removing quotes may allow a broader search: (( modified passive solution algorithms ) or ( modified delphi solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive solution algorithms") or ("modified delphi solution algorithm"))*.
