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