Perhaps you should try some spelling variations:
"modified allocation estimation algorithmssss" » "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimization algorithmssss", "modified motion estimation algorithmssss"
"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 caging optimisation algorithm") or ("modified allocation estimation algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified caging optimisation algorithm") OR ("modified allocation estimation algorithmssss")).
• Removing quotes may allow a broader search: (( modified caging optimisation algorithm ) or ( modified allocation estimation algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimisation algorithm") or ("modified allocation estimation algorithmssss"))*.
