What is the design method of interactive evolution poster? Typical modern optimization methods can only solve the display optimization problem. This paper mainly starts with the implicit optimization problem, and uses the characteristics of interactive evolutionary algorithm to let users participate in the evaluation of target individuals and calculate the optimal individuals that meet the needs of users. Finally, the method was applied to poster design and achieved good results. 1 interactive evolutionary algorithm genetic evolutionary algorithm is a random search method evolved from the evolutionary law of the genetic mechanism of "survival of the fittest, survival of the fittest" in biology. The algorithm simulates the phenomena of reproduction, crossover and gene mutation in the process of natural selection and natural inheritance, and produces the solution of the next generation. In each iteration, the solution with low fitness function value is gradually eliminated, and the solution with high fitness function value is retained. This process is repeated until a certain convergence index is met, and the traditional evolutionary algorithm is suitable for solving explicit optimization problems. Interactive evolutionary algorithm is a new algorithm developed on the basis of basic genetic algorithm, which is a process of automatically calculating fitness function value through interactive means and user's fitness evaluation during evolution. The advantage of interactive evolutionary algorithm lies in the combination of users and machines, which can solve the problems that cannot be solved in genetic operation, satisfy users' personal preferences and get the optimal solution that users are satisfied with. Interactive evolutionary algorithm is suitable for solving implicit optimization problems. . 2 algorithm design 2. 1 fitness design fitness function can measure the quality of solutions in traditional optimization problems, especially for explicit optimization problems, fitness is measured by fitness function performance indicators. For implicit optimization problems, explicit evaluation methods cannot be used, let alone accurate mathematical models, and individual populations can only be evaluated by users' subjective consciousness. The fitness value depends on the user's personal preference. Therefore, it is necessary to integrate "human preference" into typical optimization methods to obtain the optimal design scheme. In the design process, the preference value of the new population generated by each generation remains unchanged, and the individuals with the highest fitness will be directly retained to the next generation. 2.2 Coding In this paper, the poster coding is designed into two parts: Logo and Body. One chromosome represents a poster, and one chromosome is represented by an eight-bit binary code string. In this eight-bit code string, the first four digits represent the poster Logo, and the last four digits represent the poster body. In the four-digit coding of Logo, the first two represent poster style and the last two represent color; In the four-digit coding of Body, the first two digits represent poster style and the last two digits represent color. Therefore, a poster has =256 styles. According to this coding scheme, if a chromosome is 0000011,then 00 in Logo stands for style, Logo00 stands for color, Body0 1 stands for style and body01stands for color. 2.3 crossover and mutation This paper adopts two crossover operations: single-point crossover and two-point crossover. For example, a single-point hybridization has two chromosomes, which are 0000011,01001. After single-point crossover mutation, the chromosomes of the two offspring individuals are 00000 10 1kloc-0/ 011respectively, which represents the "classical" style of the Logo in the individual1 The body is gorgeous and the color is blue; In individual 2, the log "O is modern" and the color is green, the body is "Jing Yi" and the color is purple. After single-point crossover operation, four new poster styles are generated from these two poster styles. 2.4 The purpose of mutation is to improve the local search ability of evolutionary algorithm, keep the diversity of population and prevent premature phenomenon. Specifically, if an individual is represented by a binary coded symbol string, and the original gene value of a certain locus is 0, then the mutation operation will change the gene value to1; Otherwise, if the original gene value is 1, the mutation operation will change it to 0. In this paper, random point variation is used. 2.5 algorithm flow step 1: according to the actual problem coding, set the parameters of the evolutionary algorithm. Step 2: Randomly generate the initial population. Step 3: Decode and generate the individual phenotype. Step 4: Users assess personal health. Step 5: Judge whether there are individuals that users are most satisfied with. If yes, the algorithm ends and the optimal individual is output. Step 6, if not, judging whether the stop condition is met; If not, continue to step 3 after the evolutionary operation. 3 Experimental results The system first interacts with users and lists six styles of posters. Users rate each poster, and the poster with the highest score is the poster with their favorite style. The system evolves according to this method, and finally gets the poster style that users like. Poster codes and scores are as follows: poster serial number 1, chromosome code 010011,user rating 78, poster serial number 2, chromosome code 000010/,and user rating 80. 5438+0 1 1 user rating 80. The serial number of the poster is 4. The chromosome code is 0101100, and the user score is 90. The serial number of the poster is 5. Chromosome code is 10 10000 1 user rating is 60. The user rating of 438+00 100 1 is 70, and the experiment is conducted for 10 users. As shown in Figure 2, the average rating of the posters recommended by the system is 82, which indicates that the users are highly satisfied. With the increase in the number of posters selected by users when interacting with the system, the final score is getting higher and higher, indicating that the results are closer to the needs of users. This paper starts with the implicit optimization problem, adds the user's "personal preference" to the optimization problem, and uses the characteristics of users' participation in the evaluation of target individuals to get the best individuals who meet the user's personal preference needs. Finally, the method is applied to poster design, and users rate the poster style according to their own preferences. The experimental structure shows that this method has good effect. I saw many creative posters in my circle of friends, and I can turn pages. How did you make such a creative poster? Is there a tutorial? First of all, the link that can turn pages and compose pictures is H5. Of course, what you see may also be a picture with a QR code, which is essentially some web pages. Some functional interactions of the composite poster are completed through code.

Common H5 is some H5 produced by Netease. You can search in WeChat circle of friends, such as "Netease Sleeping Position Competition" H5, "Create My Strawberry Music Festival" H5, "Your Philosophical Temperament" H5 and so on. These are very common and easy to understand.

This H5 is collectively called "synthetic poster" H5.

Second, because H5 is page by page, it can become a sliding page.

Thirdly, finally, what I know here about how to do this H5 is that Epub360 can do it for free for the time being.

For detailed search _ screenshot component tutorial _ directly in Baidu.

The tutorial is as follows:

Using the Screenshot component, you can combine the contents of the H5 page into a picture for:

Make personalized invitations

One page poster

Game award certificate

puzzle ......

Sharing "screenshot" pictures is more intuitive and richer than combining thumbnails with copywriting.

First, the setting method

1. To put pictures, paragraphs and components in a page, you need to put them into a composite picture.

2. Click Add Screenshot Component.

3. Add the in-page picture/paragraph component to the screenshot component:

4._ If you live in the wrong place, you may date a dry person.

5. In this case, a click trigger is added to the "Finish" button to trigger "screen capture", thus synthesizing the picture.

6. Display the screenshot directly on the current page.

Important: Screen capture component/picture to be replaced (check Initial Hide in the right panel of the picture)

The size recommendation is consistent with the screen capture area of the screen capture component. If the screen capture area is not selected, the default screen capture area is the canvas-sized internal frame.

Generally set as shown in the figure.

The screenshot is associated with the picture to be replaced, and it will trigger-picture display after the screenshot is successful.

7. How to save the synthesized picture?

For the picture component that is finally used for display (that is, the picture used for replacement), be sure to check "QR code recognition", so that the menu of saving or forwarding will pop up after long press.

8. Size specification of composite image

There must be a bottom map. The suggested design size of this basemap is: 740x 1 136px.

The final synthesized picture takes the canvas inner frame size: 640x960px.

What are the creative skills of poster design? How to improve poster design skills? Of the 7 billion people in the world, only 3 billion are Internet users. This is why offline marketing is still hot. Printed posters can convey information to the crowd through physical posting-this traditional and powerful form of interactive communication can promote the increase of your business customers.

In order to help bring people to your store, we have collected some simple skills to make professional posters that can not only highlight your brand information, but also look fashionable on the wall.

1. Select black as the poster background.

Usually, we are used to designing posters on white canvas. However, some visually interesting posters will avoid the white background and use black. If you use black, you can consider printing information and pictures with metallic ink or even bright white, so as to make an eye-catching poster.

2. simplicity is beauty

Young designers are often keen to fill every corner of the canvas. But you don't have to do this. Simple works of art are often the most beautiful. The poster shown above is very beautiful, but it doesn't use complicated graphic elements. AnthonyLane designed these posters only by combining photos with key content. Refine and simplify your poster in this way, and only select the most critical elements and contents when making, and you can create elegant and exquisite graphic design works.

Add personalized fonts

Professional design is not limited to conventional fonts and neat layout. Try to use a font full of personality and rebellion, and eventually you will get a bold and personalized work (made by FAUPE) like the poster above. If you have enough time, take out a marker or any other writing tool you like, write down what you want to write, and create a decadent handwriting for your poster. Believe me, your handwriting is much more interesting than you think.
