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