Microsoft Math Solver is a free app that solves math and science problems, including arithmetic, algebra, trigonometry, calculus, statistics, and word problems. It provides step-by-step solutions and interactive graphs, and is available for both iOS and Android devices. Previously called Microsoft Mathematics and Microsoft Math, the app is an entry-level educational tool. Users can contact the support team at mathsupport@microsoft.com or tweet @microsoftmath with feedback. Additionally, Microsoft Math Solver can be accessed online through a website called Webmath, which generates answers to specific math questions and problems entered by the user.
Optuna is an automatic hyperparameter optimization software framework that is designed for machine learning. It features an imperative, define-by-run style interface and supports various state-of-the-art optimization algorithms, including Bayesian optimization. Optuna enables automatic searches and finds optimal hyperparameters by trial and error, which leads to excellent performance. Moreover, it supports imperative parameter definition, which provides more flexibility, and features a pruning mechanism that monitors each trial's learning curves and determines the sets of hyperparameters that will not lead to good results. Currently, the software can be used in Python and is available on GitHub. Overall, Optuna is a powerful tool that is widely used and highly recommended for hyperparameter optimization in the field of machine learning.
