Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified motion optimization algorithms" » "modified motion estimation algorithms", "modified motion estimation algorithm", "modified motion optimized algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"

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 motion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation optimisation algorithm") OR ("modified motion optimization algorithms")).
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) or ( modified motion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimisation algorithm") or ("modified motion optimization algorithms"))*.
