 Currently available line simplification algorithms are rooted in mathematics
-    and geometry, and are unfit for natural features like rivers and
-    coastlines. {\WM} algorithm is derived from cartographic knowledge, and
-    thus is well suited for natural features. We also documented our
-    implementation, which allows anyone understand the algorithm and our

+    features and created an algorithm. We implemented this algorithm and
+    documented it in great detail. Our implementation makes {\WM} algorithm
