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