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