Perhaps you should try some spelling variations:
"allocation optimisation algorithmssssssssss" » "allocation optimization algorithmssssssssss", "allocation optimization algorithmsssssssssss", "allocation estimation algorithmssssssssss", "allocation estimation algorithmsssssssssss"
"parameters optimisation algorithm" » "parameter optimization algorithm", "parameter estimation algorithm", "parameters optimization algorithms", "parameters estimation algorithm", "parameters estimation algorithms"

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 algorithmssssssssss") OR ("parameters optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"allocation optimisation algorithmssssssssss\") OR (\"parameters optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( allocation optimisation algorithmssssssssss ) OR ( parameters optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithmssssssssss") OR ("parameters optimisation algorithm"))*.
