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