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

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