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