, including a rational indivial, undertake the following activities:
first, set up a goal to solve the problem
the second is to investigate and list all the strategies available to achieve this goal< The third is to predict all the important results of each alternative strategy and evaluate the probability of the results; The fourth is to choose the strategy that
can solve the problem best or the strategy that costs the least<

rationalism theory is rooted in the rationalism and positivism in the period of enlightenment,
as well as schools of thought that try to develop isolated,
scientific knowledge to improve human conditions. I think we can choose the best plan<

in order to enjoy the maximum effect, all possible choices and the cost of each choice must be
evaluated before making a decision. However, there is bounded rationality in human decision-making, that is, in the process of looking for alternatives and calculating cost-benefit, people's ability is limited
first, there are cognitive limitations in decision makers' ability to consider various possible choices< The first mock exam is that BR / >
two is that the model assumes that the decision maker can know the consequences of every decision beforehand, and is impossible to achieve in reality.
thirdly, each policy choice anticipates a large number of favorable and unfavorable results, which makes it difficult to compare them< According to Simon's conclusion,
rational decision-making model does not maximize the value of profit minus cost in actual public decision-making,
instead, it only tends to get the criteria set by decision makers for themselves in relevant events.
With garbage classification becoming the hottest topic this summer, domestic Internet and technology companies have launched small programs, apps and other query applications, including Internet, Sogou, iFLYTEK and other companies have launched relevant intelligent query functions. Alipay, WeChat also have a lot of related small programs and small games. The characteristics of these applications are similar, mainly to query, support voice, image query
Do the emerging apps or applets really help? It's true that many users will use it when necessary. But there are also some users who, like Xiaoyu, think that search and query are troublesome“ I think the cost of littering has become higher. Some people may not have a high level of ecation, or they may be older, and the cost of learning itself is also very high. " She said
"at present, computer vision technology has been quite mature, and the fourth paradigm has a profound accumulation in the field of computer vision. Whether it can be put into use depends on the accuracy of model recognition, and the key to affect the accuracy of the model is the quality of the original data. The higher the quality and quantity of the original data, the greater the probability of training a model with high recognition accuracy. "
first, create a star shape, I use a 10 segment cylinder and delete the top and bottom surfaces
and then select its boundary to extrude a surface towards all sides
press the boundary into four sides, and pay attention to the consistency of the top, bottom, left and right points, because we will connect it in the back, and grasp the distance between the holes < B R / > to this unit into an array, first it to the position where it is connected with the body end to end as far as possible, which is very important for the welding of the back side, and then press Shift + D to and displace it repeatedly to form an array
combine them together, and then confirm merge together
next, connect this long strip to another direction with the same method to form a large piece
select and execute the bend modifier under noriner in the create deformers menu of the simulate mole
turn the handle to the position parallel to the patch, press the T key to display the operating lever, pull the blue point in the middle to make the patch curl up
after bending to the extent of end to end connection, select the seam point to merge the patch to form a bucket
Next, it's very simple to extrude the bottom, extrude the edge, extrude the thickness, and then use lattice or other deformation tools to adjust the overall size
although this example is not very impressive, this idea can be used to deal with a lot of "seemingly difficult" things, such as car tires, things with many holes, doors and windows with complex shapes, etc
Reason: no model selected for deletion. Solution: reset correctly to solve this problem
