Perhaps you should try some spelling variations:
"modified objective optimisation algorithmsss" » "modified objective optimization algorithms", "modified objective estimation algorithms", "modified objective optimization algorithmsss", "modified multiobjective optimization algorithmsss", "modified objective optimization algorithmssss", "modified objective estimation algorithmsss", "modified objective estimation algorithmssss"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter 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 objective optimisation algorithmsss") OR ("modified parameter optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimisation algorithmsss\") OR (\"modified parameter optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective optimisation algorithmsss ) OR ( modified parameter optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithmsss") OR ("modified parameter optimisation algorithm"))*.
