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