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