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

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