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