Simplex Optima vs MieChat

The general form of an optimization problem comprises a linear function of variables, also called "objective function" and a number of constraint inequalities. The app can facilitate a maximisation as well as minimisation problem bearing up to 7 variables and up to 6 contraint inequalities. The solution algorithm is implemented by constructing and manipulating the Simplex tableau before calculating the parameters for which the maximum value of the objective function is obtained.

If you are struggling to learn Japanese but don't know how to practice Japanese speaking, MieChat might be able to help you. MieChat has two unique features: 1. If you have no idea how to express yourself in Japanese, don't worry. You can input your native language, and MieChat will automatically translate it into Japanese with pronunciation. 2. If you have a rough idea of how to say something in Japanese but are not confident if it's correct, that's okay. You can input your attempt boldly, and MieChat will help you correct it to natural Japanese. In either of the above modes, by trying the same conversation several times, you will gradually learn it. You can also listen to the Japanese pronunciation while recording your own voice to compare and gradually correct your pronunciation. MieChat also comes with a cyclic memory vocabulary notebook. Words that you have remembered can be moved to the "Remembered" folder, and words you have forgotten can be moved back to the "In Memory" folder from the "Remembered" folder. By default, the Japanese kana for the words is hidden, but you can display it by pressing the word. We hope MieChat can help you with your Japanese learning.
