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

You may be able to get more results by adjusting your search query.

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