Perhaps you should try some spelling variations:
"modified near optimisation algorithm" » "modified near optimization algorithms", "modified near estimation algorithm", "modified near estimation algorithms", "modified _ optimisation algorithm", "modified network optimization algorithm", "modified seird optimisation algorithm", "modified adam optimisation algorithm"
"modified delphi solution algorithm" » "modified delphi evolution algorithm", "modified delphi convolution algorithms", "modified delphi evolutionary 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 near optimisation algorithm") or ("modified delphi solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified near optimisation algorithm") OR ("modified delphi solution algorithm")).
• Removing quotes may allow a broader search: (( modified near optimisation algorithm ) or ( modified delphi solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified near optimisation algorithm") or ("modified delphi solution algorithm"))*.
