 # Introduction 
 
-MEALPY is the largest python library for most of the cutting-edge nature-inspired meta-heuristic algorithms (population-based). Population meta-heuristic algorithms (PMA) are the most popular algorithms in the field of 
-approximate optimization.
+MEALPY is the largest python library in the world for most of the cutting-edge meta-heuristic algorithms 
+(nature-inspired algorithms, black-box optimization, global search optimizers, iterative learning algorithms, 
+continuous optimization, derivative free optimization, gradient free optimization, zeroth order optimization, 
+stochastic search optimization, random search optimization). These algorithms belong to population-based algorithms 
+(PMA), which are the most popular algorithms in the field of approximate optimization.
