Perhaps you should try some spelling variations:
"modified notion estimation algorithmssss" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified motion estimation algorithmssss"
"modified lighting optimization algorithms" » "modified lighting optimisation algorithm", "modified lighting estimation algorithms", "modified lighting estimation algorithm", "modified staffing optimization algorithms", "modified caging optimization algorithms"

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 lighting optimization algorithms") OR ("modified notion estimation algorithmssss"))~.
• Removing quotes may allow a broader search: (( modified lighting optimization algorithms ) or ( modified notion estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified lighting optimization algorithms") or ("modified notion estimation algorithmssss"))*.
