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