Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified saline » modified caging, modified male, modified passive
df optimization » _ optimization, qoe optimization, _ optimisation
modified df » modified _, modified adam, 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 saline solution algorithm ) OR ( modified df optimization algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified saline solution algorithm ) OR ( modified df optimization algorithms ))*.
