Perhaps you should try some spelling variations:
"modified invasive optimization algorithmss" » "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive optimization algorithmsss", "modified invasive optimisation algorithmss", "modified invasive estimation algorithmss", "modified passive optimization algorithmss"
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization 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 optimization algorithm\") OR (\"modified invasive optimization algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) OR ( modified invasive optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithm") OR ("modified invasive optimization algorithmss"))*.
