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

You may be able to get more results by adjusting your search query.

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