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