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