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