Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
bi1 optimisation » _ optimisation, _ optimization, qoe optimization
modified bi1 » modified _
modified df » modified _, modified adam
df solution » _ solution, drug solution, up solutions

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified df solution algorithm ) OR ( modified bi1 optimisation algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified df solution algorithm ) OR ( modified bi1 optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified df solution algorithm ) OR ( modified bi1 optimisation algorithm ))*.
