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