Perhaps you should try some spelling variations:
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"
"modified nodal solution algorithm" » "modified nodal evolution algorithm", "modified nodal convolution algorithms", "modified nodal evolutionary algorithm", "modified adam solution algorithm", "modified near solution algorithm", "modified model solutions algorithm", "modified norway solution algorithm", "modified nacl solution algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified nodal solution algorithm") or ("modified objective predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified nodal solution algorithm") OR ("modified objective predation algorithm")).
• Removing quotes may allow a broader search: (( modified nodal solution algorithm ) or ( modified objective predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified nodal solution algorithm") or ("modified objective predation algorithm"))*.
