Incremental Cardinality Constraints for MaxSAT

open access: yes, 2014
Maximum Satisfiability (MaxSAT) is an optimization variant of the Boolean Satisfiability (SAT) problem. In general, MaxSAT algorithms perform a succession of SAT solver calls to reach an optimum solution making extensive use of cardinality constraints ...

The variant ‘his‐box’ of the C18‐Δ9‐PUFA‐specific elongase IgASE1 from Isochrysis galbana is essential for optimum enzyme activity [PDF]

open access: yesFEBS Letters, 2003
IgASE1, a C18‐Δ9‐polyunsaturated fatty acid‐specific fatty acid elongase component from Isochrysis galbana, contains a variant histidine box (his‐box) with glutamine replacing the first histidine of the conserved histidine‐rich motif present in all other known equivalent proteins. The importance of glutamine and other variant amino acid residues in the
