One ． General

National College Students electrical mathematical modeling competition （ Hereinafter referred to as competition ） It is a science and technology activity for national college students sponsored by the special committee of Electrotechnics and mathematics of China Electrical Engineering Society , The purpose is to improve students' comprehensive quality 、 Enhance innovation knowledge 、 Cultivate students' ability to apply mathematical knowledge to solve practical engineering problems , Stimulate students' enthusiasm in learning mathematics , At the same time, it will also promote the process of teaching reform and educational innovation in Colleges and Universities .
Two ． Competition content

The competition topic usually comes from electricians 、 Modern mathematics and economic management , After appropriate simplification 、 Practical problems of processing , It mainly includes ：

1． Information processing problems ;

2． Control theory and Application ;

3． Operational research and decision making ;

4． Problems related to circuit and electromagnetic field theory .

The participating students should have studied the engineering mathematics courses in ordinary colleges and universities and the professional basic knowledge of related majors , Participants are not required to have in-depth expertise in advance . Competition topics are more flexible , It can enable the participating students to give full play to their creativity Ability . Contestants should ask according to the title , Complete a hypothesis including the model 、 Establish and solve 、 Algorithm design and computer implementation 、 Analysis and test of results 、 The improvement of the model （ Answer sheet ）. answer sheet The assessment is based on the rationality of assumptions 、 Creativity of modeling 、 The feasibility of the results and the clarity of the text are the main criteria .
3、 ... and ． Competition form 、 Rules and discipline
