Predicted Calc is a calculator that made by android base, and use genetic algorithm to get unknown value of variables that typed on the equation.  Therefore, this app can also be use for finding root of polynomial equation, like an examples below: For example to find root of equation: x 2 -2*x-3=0 The steps is: Copy and write the equation without x and y, and with math sign operation, for example by using xo, so the equation can be writed as xo*xo-2*xo-3=0, because  x and y was used by Predicted Calc as input variables. Press calculate botton to predict one of roots. Wait until Predicted Calc, approach the best value can be reach. Because using prediction method, Predicted Calc give error result, this error show how far the prediction give best value that can be reach by your device on that calculation, another calculation could be give the different result as same as or more better error value. Predicted Calc will give the result -1 and 3 with error=0, l...

One more, Computational Lab., Dept. of Physics, UB release new android app today, 1 Juli 2015. This app called as Date Calculator and have functionality as general calculator, but with different method where the calculation is based on date data. It's that mean all math operation on this app is basically to optimize user to do math calculation accordingly date math operation. And so in this calculator we will not find minus value, because in Julian Date the minimum value is zero.   Figure 1. The main idea of Date Calculator is because mostly of us do math calculation based on date data. especially for give dateline to some project, with just type number of day that given, we need to make sure what the date is it happen. However the math operation is the basic operation like addition, subtraction , multiplication and division, but if we directly calculate manually, sometimes could be little difficult and we have to see calender to validate.  For example, like in ...

Caliper Simulator is an app that designed to simulate the technique of how to read of Caliper measurement results. This app is one of Computational Lab of Department Physics, UB productivity to increase the passion of learning about physics on Elementary Physics Lab. You can long press the Caliper Image to interact with it, and learn how to measure bolts, head bolts, small iron and something else. This is Free on Google Play Have Fun!

Predicted Calc is an app that designed as the implementation of Genetic algorithm method. It's a calculator and was created by members of Computational Physics Laboratory, Department of Physics, Faculty of Mathematics and Sciences, University of Brawijaya, Malang, East Java, Indonesia.    The main idea of this algorithm, we called as the progressive error prediction. Where with that algorithm, this App can do the numerical calculation with the ability to predicted many unknown variables, many inputs value and many form of equation, of course with small error value. Just type your equation and press CALCULATE button, and let Predicted Calc predicted all unknown variables as you need to their real value. another video tutorial app Get Predicted Calc Pro on Google Play  or you can get the free version at Get Free Version of Predicted Calc on Google Play
