Perhaps you should try some spelling variations:
solutions algorithm » evolution algorithm, evolutionary algorithm
objective solution » objective evolutionary, objective allocation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
up solutions » _ solutions, _ solution
modified up » modified _, modified df, modified bi1

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 objective solution algorithm ) OR ( modified up solutions algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified objective solution algorithm ) OR ( modified up solutions algorithm ))*.
