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

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