Perhaps you should try some spelling variations:
"modified allocation optimized algorithms" » "modified allocation optimization algorithms", "modified allocation optimized algorithm", "modified allocation optimizer algorithms"
"modified invasive solution algorithm" » "modified invasive evolution algorithm", "modified invasive convolution algorithms", "modified invasive evolutionary algorithm", "modified passive solution 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 optimized algorithms\") OR (\"modified invasive solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified allocation optimized algorithms ) OR ( modified invasive solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimized algorithms") OR ("modified invasive solution algorithm"))*.
