Perhaps you should try some spelling variations:
"allocation optimisation algorithmssssssss" » "allocation optimization algorithmssssssss", "allocation optimization algorithmsssssssss", "allocation estimation algorithmssssssss", "allocation estimation algorithmsssssssss"
"parameters optimisation algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters estimation algorithm", "parameters estimation 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: (("allocation optimisation algorithmssssssss") or ("parameters optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("allocation optimisation algorithmssssssss") OR ("parameters optimisation algorithm")).
• Removing quotes may allow a broader search: (( allocation optimisation algorithmssssssss ) or ( parameters optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithmssssssss") or ("parameters optimisation algorithm"))*.
