Perhaps you should try some spelling variations:
"modified changing solution algorithm" » "modified changing evolution algorithm", "modified changing convolution algorithms", "modified changing evolutionary algorithm", "modified caging solution algorithm", "modified charging station algorithm"
"modified objective allocation algorithmss" » "modified objective location algorithmss", "modified objective allocation algorithms", "modified objective allocation algorithmic"

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 changing solution algorithm\") OR (\"modified objective allocation algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified changing solution algorithm ) OR ( modified objective allocation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified changing solution algorithm") OR ("modified objective allocation algorithmss"))*.
