Perhaps you should try some spelling variations:
"modified static optimization algorithms" » "modified static optimisation algorithm", "modified static estimation algorithms", "modified static estimation algorithm", "modified stage optimization algorithms", "modified stochastic optimization algorithms", "modified staffing 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 static optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified invasive evolution algorithm ) or ( modified static optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive evolution algorithm") or ("modified static optimization algorithms"))*.
