Perhaps you should try some spelling variations:
"modified notion optimisation algorithmss" » "modified notion optimization algorithms", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimization algorithmsss", "modified notion estimation algorithmss", "modified notion estimation algorithmsss", "modified network optimization algorithmss"
"modified lighting optimisation algorithm" » "modified lighting optimization algorithms", "modified lighting estimation algorithm", "modified lighting estimation algorithms", "modified caging optimisation 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 lighting optimisation algorithm") OR ("modified notion optimisation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified lighting optimisation algorithm\") OR (\"modified notion optimisation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified lighting optimisation algorithm ) OR ( modified notion optimisation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified lighting optimisation algorithm") OR ("modified notion optimisation algorithmss"))*.
