Perhaps you should try some spelling variations:
"parameters optimisation algorithmssss" » "parameters optimization algorithms", "parameter optimization algorithmssss", "parameter estimation algorithmssss", "parameters optimization algorithmsssss", "parameters estimation algorithmssss", "parameters estimation algorithmsssss"
"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: "((\"allocation optimisation algorithm\") OR (\"parameters optimisation algorithmssss\"))~".
• Removing quotes may allow a broader search: (( allocation optimisation algorithm ) OR ( parameters optimisation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("allocation optimisation algorithm") OR ("parameters optimisation algorithmssss"))*.
