Optimization commenced with the parameterization of aerodynamic devices via continuous and discrete variables
. Forty-six continuous variables were derived to define the chord length, relative position, geometric angle, overlap and gap spacing between elements on the full vehicle.
For the discrete-problem version, discrete variables
are selected from the set:
Compared with topology optimization with continuous variables, the researches on topology optimization of trusses with discrete variables
are much less.
Statistical correlation means that, given two discrete variables
X and Y measured for each case in a sample, variation in X corresponds (or on the contrary, does not) to variation in Y
At the other end there is a port information which is characterized by discrete variables
, speed and strength, V * c and f * c .
Then, the discrete variables
will be relaxed and they will be considered as real numbers.
2) Formulas given in theorem and its corollary, both for continuous and discrete variable
, also apply if some of the extremities of support intervals [l(f),r(f)] and [l(g),r(g )] of functions f and g are infinite.
Comparison of G3-GA, DE with IABC for reconfigurable antenna array with discrete variable
. Algorithm without ADR with ADR ADR fitness fitness G3-GA  0.619 5.8026 0.2630 DE  0.36 4.7190 0.16 MABC  0.16 4.76 0.22 IABC 0.16 4.26 0.09 Table 4.
Then, following the usual procedure of the method of lines, [r.sup.*] is treated as a discrete variable
and then [t.sup.*] is integrated as a continuous one.
RONVEAUX, Onfourth-Order difference equations for orthogonal polynomials of a discrete variable
: derivation, factorization and solutions, J.
of York explained that "this scheme teleclones continuous variable quantum information, not just discrete variable
quantum information." One advantage to continuous variable methods is the throughput.
Tillage practices were a discrete variable
with eight categories representing different types of tillage systems.
