Perhaps you should try some spelling variations:
"allocation optimisation algorithm" » "allocation optimization algorithm", "allocation optimization algorithms", "allocation estimation algorithm", "allocation estimation algorithms"
"notion optimisation algorithmssssssssssssssss" » "notion optimization algorithmsssssssssssssssss", "notion estimation algorithmssssssssssssssss", "notion estimation algorithmsssssssssssssssss", "network optimization algorithmssssssssssssssss"

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: (("notion optimisation algorithmssssssssssssssss") OR ("allocation optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( notion optimisation algorithmssssssssssssssss ) or ( allocation optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("notion optimisation algorithmssssssssssssssss") or ("allocation optimisation algorithm"))*.
