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

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