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