For the discrete-problem version, discrete variables
are selected from the set:
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
Mine blast algorithm for optimization of truss structures with discrete variables
The proposed BLGA can handle MINLBLP with both continuous and discrete variables
with one or multiple independent nonlinear and nonconvex lower-level models.
However, these methods are faced with serious limitations in managing non-linear and discontinuous functions and have many local minimum and include discrete variables
Further, Mike showed that models of discrete variables
that allow for changes in variance outperform constant variance specifications.
The MINLP represents a mathematical programming technique which executes the discrete optimization of discrete variables
simultaneously with the continuous optimization of continuous variables.
At the other end there is a port information which is characterized by discrete variables
, speed and strength, V * c and f * c .
It is generally believed that the genetic algorithm (GA) and ant colony optimization (ACO) algorithm are more suitable to handle discrete optimization problems, because of the GA and ACO using discrete coding method and dealing directly with discrete variables
1 shows impulse responses (5) accessible for computations in respect to discrete variables
k and n and parameter [alpha] = -0.
Both groups were also compared with respect to discrete variables
as gender, presence of a ureteric stent, previous ESWL and side of treatment.
Among them, ten phase coefficients are represented as discrete variables
, and the other ten are represented as continuous variables.
