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