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

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: "((\"allocation optimisation algorithm\") OR (\"parameters optimisation algorithmssssssssss\"))~".
• Removing quotes may allow a broader search: (( allocation optimisation algorithm ) OR ( parameters optimisation algorithmssssssssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithm") OR ("parameters optimisation algorithmssssssssss"))*.
