Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"model using methods algorithm" » "model nursing methods algorithm", "model making methods algorithm", "model counting methods algorithm", "code using methods algorithm", "models nursing methods algorithm", "powder using methods 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 allocation optimisation algorithm\") OR (\"model using methods algorithm\"))~".
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) OR ( model using methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimisation algorithm") OR ("model using methods algorithm"))*.
