Perhaps you should try some spelling variations:
"modified objective optimisation algorithmss" » "modified objective optimization algorithms", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimization algorithmsss", "modified objective estimation algorithmss", "modified objective estimation algorithmsss", "modified objective optimization algorithmss", "modified multiobjective optimization algorithmss"
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"

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 objective optimisation algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimisation algorithm") OR ("modified objective optimisation algorithmss")).
• Removing quotes may allow a broader search: (( modified parameters optimisation algorithm ) or ( modified objective optimisation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimisation algorithm") or ("modified objective optimisation algorithmss"))*.
