The algorithm introduction below is an introduction to the research being done by Teacher Lu Wenlian and his team.
Teams working in related industries who need algorithm design and optimization are also welcome to contact us.
Mr. Hua Luogeng is a pioneer in the promotion of mathematical methods. For more than 20 years, regardless of fatigue and old age, he traveled all over the country to promote the "double method" (optimization method and overall planning method.)
The three principles he proposed still seem to have strong reference significance today.
When Hua Luogeng talked about his experience in promoting mathematical methods, he put forward three principles:
(1) For whom? What's the purpose?
(2) What technology is used?
(3) How to promote?
Regarding (1), to find a common language between experts and workers, there must be a common goal in order to open the way for the production of a common language.
Regarding (2), he emphasized three aspects:
The first is mass nature, that is, the methods proposed must be understood, learned, used and effective by the masses.
The second is practicality. Each method must be practiced before being promoted to test the applicable scope of the method, and then be promoted within this scope. We cannot copy foreign things mechanically.
The third is theoretical, which must have a high theoretical level, because only with theory can we understand things in a simple and profound way, only with theory can we distinguish the quality of methods, and only with theory can we create new methods.
For (3), we need to do it ourselves, first in a small area, starting with a workshop or a project, and then gradually expand and achieve results.
Hua Luogeng chose the optimization method and the overall planning method based on these principles. Through research, he learned about some management issues at the overall level of production, such as production arrangement, progress, construction period, etc. In 1964, he took the foreign CPM (Critical Line Method) and PERT (Plan Review Method) methods as the core, refined and processed them, eliminated the false and retained the true, and popularized and visualized it, and proposed a Chinese-style overall planning method.
"He used the factory holidays to go back to school to check the information and found the latest 4 papers on parametric curves and bicubic surface fitting, including the DeBoer-Cox algorithm of B-splines that is now popular in computer-aided design systems. Mr. Su translated them all and compiled "Selected Translations of Spline Fitting" in the name of the Department of Mathematics of Fudan University and the Hull Workshop of Jiangnan Shipyard. Mr. Su also once went to Jiangnan Shipyard to do research on mathematical hull lofting.
The preface of the book clearly states: "These articles were all translated by Professor Su Buqing." Mr. Su's work not only directly guided our work, but also played a guiding role in the nationwide mathematics stakeout work.
Under Mr. Su's guidance, we used a combination of surfaces and curves instead of just curves to solve this problem. The algorithm program completed based on this idea (mainly completed by Xin Yuanlong and Gu Lingtong) successfully calculated several different types of ships with good results. The hard work finally paid off.
"
Although times and environments are different, the spirit still needs to be passed on.
We look forward to the transformation of mathematical achievements to bear fruit.
