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