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

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

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