其实也算是 TSP 问题的一种思路.


The “Plus Minus Problem” asks whether or not it’s possible, given the numbers 1 to n, to add and subtract them in some manner so that the total sum is zero. The problem may not have many practical applications, but it’s a great way to illustrate how a little bit of reasoning can save you from exponential-time algorithms.


涉及数论问题时, Python 反而是最趁手的工具, 毕竟形式上太直觉了.


HCrystalBall wraps time series forecasting projects like fbprophet, arima with autoarima, exponential smoothing from statsmodels, and (t)bats, and unifies them under a scikit-learn compatible interface so that you can leverage features like scikit-learn pipelines.

Thanks to high-quality pretrained models, Wikipedia, and Streamlit, deploying a state-of-the-art question answering system has never been easier!

旅行商艺术模块, 太魔幻了,

TSP 问题的研究,直接加速了 CPU 自动设计进程, 是个非常复杂又实用的领域, 没想到 Py 也入侵了这一领域.







FormHelper *gui = new FormHelper(screen);
ref<Window> window = gui->add_window(Vector2i(10, 10), "Form helper example");
gui->add_group("Basic types");
gui->add_variable("bool", bvar);
gui->add_variable("string", strvar);

gui->add_group("Validating fields");
gui->add_variable("int", ivar);
gui->add_variable("float", fvar);
gui->add_variable("double", dvar);

gui->add_group("Complex types");
gui->add_variable("Enumeration", enumval, enabled)
   ->setItems({"Item 1", "Item 2", "Item 3"});
gui->add_variable("Color", colval);

gui->add_group("Other widgets");
gui->add_button("A button", [](){ std::cout << "Button pressed." << std::endl; });


看起来像是 C++ 代码.
