Description
One, technical fields
The present invention relates to a kind of teaching aid, belong to instructional technology and artificial intelligence field.
Two, background technologies
With the development of computer and artificial intelligence technology, evolution algorithm is widely used for applied mathematics, Logistics Engineering, industry
The teaching of the specialty such as engineering, Computer Science and Technology, mechanization and automation and engineer applied.Evolution algorithm has many changes
Change：There are different genetic expression ways, different intersections and mutation operator, different regeneration and system of selection, its inspiration
Come from the biological evolution of the Nature.Compared with the optimized algorithm such as traditional method based on calculus and the method for exhaustion, evolution algorithm
Be it is a kind of it is ripe there is high robust and the global optimization method of broad applicability, with self-organizing, adaptive, self study
Characteristic, can not be limited by problem property, effectively handle the insoluble challenge of traditional optimized algorithm.
The evolutionary operator species such as intersection, variation and selection are various, often combined with art.Imparted knowledge to students in evolutionary operator
Cheng Zhong, student generally reflects that the calculating process complexity of evolutionary operator is abstract, hard to understand.In teaching, shape is generally used at present
As intuitively program flow diagram.Program flow diagram is made up of some defined figures and flowline, for describing the computing of algorithm
Process, can clearly order of representation structure, construction of condition and loop structure, but still need every kind of with natural language expressing
The calculating process of inside configuration.The analysis and understanding of natural language needs domain knowledge, it is impossible to accomplish visual in image.Student is in study
During, often understand a step, forget previous step, it is dull and obscure, it is necessary to patient and willpower.
Evolutionary operator simulates biological evolution process by genetic change, expresses the solution or optimization of engineering problem
Deng calculating process.Gene are the chromosome sequences for carrying hereditary information, are the basic genetic units of individual control character.
So-called crossover operator refers to the computing for a part for two parent individuality chromosome sequences being replaced mutually and being generated new individual.Become
Exclusive-OR operator is that the genic value on some locus to the individual chromosome sequence in colony changes.
For the creativity consciousness of training student, creation enthusiasm is excited, the calculating process of evolutionary operator is become like row's building blocks
Visual in image and rich in entertaining as picture arrangement game, the present invention proposes a kind of evolutionary operator teaching aid.
The three, content of the invention
It is an object of the invention to provide a kind of evolutionary operator teaching aid, the calculating process of evolutionary operator can be made visual in image and
Rich in entertaining, the calculating process for being easy to student's profound understanding abstract；The creativity consciousness of training student, excites creation enthusiasm.
A kind of evolutionary operator teaching aid includes bottom plate 1, terminal box 2 and Graphic Panel 5, as shown in Figure 1.Carried on the bottom plate 1
Spare block holding tank 8, the chromosome block 7 standby for accommodating.In the terminal box 2 carry battery compartment 3, for accommodate battery and
The wiring of light circuit.With individual headlamp switch 4 and gene lamp switch 6 on the Graphic Panel 5, connection chromosome block 7 is used for
It is illustrated in the calculating process of evolutionary operator, individual includes the change procedure of chromosome, makes the calculating process image of evolutionary operator
Intuitively.
