Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified lighting optimized algorithms" » "modified lighting optimized algorithm", "modified lighting optimizer algorithms", "modified lighting optimization algorithms", "modified caging optimized algorithms"

Try widening your search to All Fields.

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 optimized algorithms") or ("modified allocation optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified lighting optimized algorithms") OR ("modified allocation optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified lighting optimized algorithms ) or ( modified allocation optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified lighting optimized algorithms") or ("modified allocation optimisation algorithm"))*.
