Perhaps you should try some spelling variations:
"modified location optimization algorithmssss" » "modified location optimization algorithms", "modified location optimisation algorithm", "modified allocation optimization algorithmssss", "modified static optimization algorithmssss", "modified carbon optimization algorithmssss"
"modified notion estimation algorithm" » "modified motion estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion estimation algorithm") OR ("modified location optimization algorithmssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion estimation algorithm\") OR (\"modified location optimization algorithmssss\"))".
• Removing quotes may allow a broader search: (( modified notion estimation algorithm ) OR ( modified location optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithm") OR ("modified location optimization algorithmssss"))*.
