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