A few days ago, the experiment of the algorithm class required visualization, and I did n’t move it for a long time. Then some big guys said that they used easyx. I did n’t teach this thing how to use it. Then I was very annoyed looking for tutorials on the Internet, and found that there was no instruction on how to use them. They all said that there was a manual ( link ), and it was enough to call the function by myself, so I started the journey of checking the function. I have to say that the manual is still very good, and it will be used after reading it. Because the experiment is relatively simple, only basic operations such as drawing lines, drawing circles, writing, and changing colors can be used. Then I think easyx is really fragrant. It is very troublesome to find the position when painting. It took a night to finish the painting. The result is below.
The first one is convex hull, although it is arranged in order, but it is almost crying at the end of the connection between the upper package and the lower package. It has been debugging for a long time. The easyx drawing point is really not good, too small and too light, It is best to draw a circle and fill it. Then there is the 01 backpack. This table may have been drawn for 3 hours, mainly the position of the debugging line, the size of the table, the position of the word, the color of the selected item or something. Then there is the backpack of the greedy method, this one is even better, the integer is okay, you can turn it into a character one by one, but the decimal ... I have a clever move, expand it by 1000 times, and then add before the countdown three Decimal point.
There are many courses in the back that should also try to use easyx to achieve visualization or make a beautiful interface.
Having said that, in fact, the biggest gain is the courage to face the problem. Some things, if you do n’t try it yourself, just listen to others, it feels difficult, and you can never learn. Trying it is a gain even without learning. In fact, I almost didn't want to achieve visualization, but for the purpose of score! ! (escape
