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 adam solutions algorithm" » "modified adam solution algorithm", "modified adam evolution algorithm", "modified adam evolutionary algorithm", "modified df solutions algorithm", "modified near solutions 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 allocation optimisation algorithm") or ("modified adam solutions algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation optimisation algorithm") OR ("modified adam solutions algorithm")).
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) or ( modified adam solutions algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimisation algorithm") or ("modified adam solutions algorithm"))*.
