Perhaps you should try some spelling variations:
"modified objective convolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm"
"modified nodal optimisation algorithm" » "modified nodal optimization algorithms", "modified nodal estimation algorithm", "modified nodal estimation algorithms", "modified global optimization algorithm", "modified adam optimisation algorithm", "modified near optimisation 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 objective convolution algorithms") OR ("modified nodal optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective convolution algorithms\") OR (\"modified nodal optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified objective convolution algorithms ) OR ( modified nodal optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithms") OR ("modified nodal optimisation algorithm"))*.
