Perhaps you should try some spelling variations:
"modified topology optimization algorithm" » "modified topology optimization algorithms", "modified topology optimisation algorithm", "modified topology estimation algorithm"
"modified based solution algorithm" » "modified based evolution algorithm", "modified based convolution algorithms", "modified based evolutionary algorithm", "modified male solution algorithm", "modified based solutions algorithm", "modified water solution algorithm", "modified based evaluation algorithm"

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 based solution algorithm\") OR (\"modified topology optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified based solution algorithm ) OR ( modified topology optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified based solution algorithm") OR ("modified topology optimization algorithm"))*.
