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