Perhaps you should try some spelling variations:
"modified write optimization algorithms" » "modified write optimisation algorithm", "modified write estimation algorithms", "modified write estimation algorithm", "modified game optimization algorithms", "modified qoe optimization algorithms", "modified stage optimization algorithms"
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive solution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"

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 write optimization algorithms\") OR (\"modified invasive convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified write optimization algorithms ) OR ( modified invasive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified write optimization algorithms") OR ("modified invasive convolution algorithms"))*.
