Frequently Asked Questions (8)
Q2. How many directional superconducting quantum interference devices were assumed?
Sixteen -directional superconducting quantum interference device (SQUID) magnetometers, capable of measuring parallel magnetic fields, were assumed.
Q3. What is the predetermined probability of the GA?
The predetermined probability of 0.015 is generally used; however, in this paper, larger values are used to alleviate premature convergence due to local optimization.
Q4. What is the objective function of the GA?
To apply GA, the objective function (cost) is defined to minimize the difference between the measured (forward) and reconstructed magnetic field at each sensor position.
Q5. What is the sensitivity of a gene?
More sensitive genes are selected formutation and the number of genes selected for mutation is defined as follows:(1)where is the number of genes that change their states , is the number of genes that have positive sensitivity values, and is a probability between 0 and 1, which will be explained again at the end of this section.
Q6. What kind of reconstruction problem can be classified as a topology optimization problem?
11Some kinds of reconstruction problems such as a crack detection problem (materials to be reconstructed: air and conductor) can be classified as a topology optimization problem.
Q7. What is the meaning of the word "Linear string"?
A. 2-D Encoding for GAA linear string is a symbolic feature of GAs, and most GA implementations have been based on linear encodings [13].
Q8. What was the objective function that needed to be minimized?
The objective function that needed to be minimized was defined as(4)where represents -directional magnetic flux density at a measuring point [in Fig. 10(b)], and is the standard deviation of the -directional flux density at all measuring points.
