Perhaps you should try some spelling variations:
"modified drug convolution algorithms" » "modified drug evolution algorithm", "modified drug solution algorithm", "modified drug solution algorithms", "modified df convolution algorithms", "modified orca convolution algorithms"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified drug convolution algorithms") OR ("modified objective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified drug convolution algorithms\") OR (\"modified objective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified drug convolution algorithms ) OR ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified drug convolution algorithms") OR ("modified objective optimisation algorithm"))*.
