Perhaps you should try some spelling variations:
"modified topology optimization algorithm" » "modified topology optimization algorithms", "modified topology optimisation algorithm", "modified topology estimation algorithm"
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution 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 topology optimization algorithm\") OR (\"modified learning convolution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified topology optimization algorithm ) OR ( modified learning convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified topology optimization algorithm") OR ("modified learning convolution algorithm"))*.
