Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static estimation algorithms", "modified static estimation algorithm", "modified static optimized algorithms", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing optimization algorithms"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

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