Perhaps you should try some spelling variations:
"modified topology optimisation algorithm" » "modified topology optimization algorithms", "modified topology estimation algorithm", "modified topology estimation algorithms", "modified topology optimization algorithm", "modified policy optimization algorithm"
"modified delphi convolution algorithms" » "modified delphi evolution algorithm", "modified delphi solution algorithm"

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 optimisation algorithm") OR ("modified delphi convolution algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified topology optimisation algorithm\") OR (\"modified delphi convolution algorithms\"))*".
• Removing quotes may allow a broader search: (( modified topology optimisation algorithm ) OR ( modified delphi convolution algorithms ))*.
