QuantConnect supports coding in Python and C#, but also supports other languages through its open-source project, the Lean Algorithmic Trading Engine (LEAN). [8] [9] [10] LEAN is an open-source algorithmic trading engine that allows users to do the same algorithm design, backtesting, and trading that they can do on the website. Once users code ...
After version 3.4.2 Lean 3 was officially end-of-lifed while development of Lean 4 began. In this interim period members of the Lean community developed and released unofficial versions up to 3.51.1. In 2021, Lean 4 was released, which was a reimplementation of the Lean theorem prover capable of producing C code which is then compiled, enabling ...
An interactive proof session in CoqIDE, showing the proof script on the left and the proof state on the right. In computer science and mathematical logic, a proof assistant or interactive theorem prover is a software tool to assist with the development of formal proofs by human–machine collaboration.
A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command lines. Command-line interfaces emerged in the mid-1960s, on computer terminals , as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards .
Lean thinking has to be understood well by all members of a project, before implementing in a concrete, real-life situation. "Think big, act small, fail fast; learn rapidly" [ 8 ] – these slogans summarize the importance of understanding the field and the suitability of implementing lean principles along the whole software development process.
Signboard. In manufacturing, andon (Japanese: アンドン or あんどん or 行灯) is a system which notifies managerial, maintenance, and other workers of a quality or process problem.
The Common Language Infrastructure (CLI) is an open specification and technical standard originally developed by Microsoft and standardized by ISO/IEC (ISO/IEC 23271) and Ecma International (ECMA 335) [1] [2] that describes executable code and a runtime environment that allows multiple high-level languages to be used on different computer platforms without being rewritten for specific ...
Cube kaizen describes the situation where all the points of the planes are connected to each other and no point is disjointed from any other. This would resemble a situation where Lean has spread across the entire organization. Improvements are made up and down through the plane, or upstream or downstream, including the complete organization ...
