+# Automatic Model Architecture Search for Reading Comprehension
+This example shows us how to use Genetic Algorithm to find good model architectures for Reading Comprehension task.
+
+## Search Space
+Since attention and recurrent neural network (RNN) module have been proven effective in Reading Comprehension.
+We conclude the search space as follow:
+
+1. IDENTITY (Effectively means keep training).
+2. INSERT-RNN-LAYER (Inserts a LSTM. Comparing the performance of GRU and LSTM in our experiment, we decided to use LSTM here.)
+3. REMOVE-RNN-LAYER
+4. INSERT-ATTENTION-LAYER(Inserts a attention layer.)
+5. REMOVE-ATTENTION-LAYER
+6. ADD-SKIP (Identity between random layers).
+7. REMOVE-SKIP (Removes random skip).
+

+
+## New version
+Also we have another version which time cost is less and performance is better. We will release soon.
+
