Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified changing convolution algorithms" » "modified changing evolution algorithm", "modified changing solution algorithm", "modified learning convolution algorithms", "modified caging convolution algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified changing convolution algorithms") OR ("modified allocation optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing convolution algorithms\") OR (\"modified allocation optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified changing convolution algorithms ) OR ( modified allocation optimisation algorithm ))*.
