Perhaps you should try some spelling variations:
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithm", "designed network optimization algorithm"
"modified changing solution algorithm" » "modified changing evolution algorithm", "modified changing convolution algorithms", "modified changing evolutionary algorithm", "modified caging solution algorithm", "modified charging station algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("defined network optimization algorithm") OR ("modified changing solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network optimization algorithm\") OR (\"modified changing solution algorithm\"))".
• Removing quotes may allow a broader search: (( defined network optimization algorithm ) OR ( modified changing solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithm") OR ("modified changing solution algorithm"))*.
