Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms", "modified _llocation optimisation algorithm", "modified dfllocation optimisation algorithm", "modified adamllocation optimisation algorithm"
"modified a predation algorithm" » "modified a predators algorithm", "modified a estimation algorithm", "modified _ predation algorithm", "modified a prediction algorithm", "modified orca predation algorithm", "modified df predation algorithm", "modified adam predation 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 a predation algorithm") or ("modified allocation optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified a predation algorithm") OR ("modified allocation optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified a predation algorithm ) or ( modified allocation optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified a predation algorithm") or ("modified allocation optimisation algorithm"))*.
