Perhaps you should try some spelling variations:
"modified topology optimization algorithms" » "modified topology optimisation algorithm", "modified topology estimation algorithms", "modified topology estimation algorithm"
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified topology optimization algorithms\") OR (\"modified notion optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified topology optimization algorithms ) OR ( modified notion optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified topology optimization algorithms") OR ("modified notion optimization algorithms"))*.
