Perhaps you should try some spelling variations:
"modified based investigation algorithms" » "modified based estimation algorithms", "modified based estimation algorithm", "modified raising investigation algorithms", "modified effect investigation algorithms", "modified male investigation algorithms"
"modified notion optimized algorithms" » "modified notion optimized algorithm", "modified notion optimizer algorithms", "modified notion optimization 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 based investigation algorithms") OR ("modified notion optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified based investigation algorithms\") OR (\"modified notion optimized algorithms\"))".
• Removing quotes may allow a broader search: (( modified based investigation algorithms ) OR ( modified notion optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified based investigation algorithms") OR ("modified notion optimized algorithms"))*.
