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 evolution algorithm" » "modified invasive solution algorithm", "modified invasive evolutionary algorithm", "modified invasive convolution algorithms", "modified invasive ventilation algorithm", "modified passive evolution algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive evolution algorithm") OR ("modified write optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified invasive evolution algorithm ) or ( modified write optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive evolution algorithm") or ("modified write optimization algorithms"))*.
