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"
"modified model selection algorithm" » "modified model solution algorithm", "modified model estimation algorithm", "modified model reduction algorithm", "modified market selection algorithm", "modified male selection 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 (\"modified model selection algorithm\"))~".
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) OR ( modified model selection algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimisation algorithm") OR ("modified model selection algorithm"))*.
