Perhaps you should try some spelling variations:
"allocation optimisation algorithmssssss" » "allocation optimization algorithms", "allocation optimization algorithmssssss", "allocation optimization algorithmsssssss", "allocation estimation algorithmssssss", "allocation estimation algorithmsssssss"
"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.

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