Perhaps you should try some spelling variations:
"allocation optimization algorithmssss" » "allocation optimisation algorithm", "allocation optimisation algorithmsss", "allocation estimation algorithmssss", "allocation estimation algorithmsss", "location optimization algorithmssss"
"parameters optimization algorithms" » "parameter optimization algorithms", "parameter estimation algorithms", "parameters optimisation algorithm", "parameters estimation algorithms", "parameters estimation algorithm"

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