Perhaps you should try some spelling variations:
"modified allocation optimisation algorithms" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm"
"modified adaptive optimization algorithms" » "modified adaptive optimisation algorithm", "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified objective optimization algorithms", "modified adaptive quantization algorithms", "modified static optimization algorithms", "modified passive optimization algorithms"

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

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