+## Future research and contributions
+
+I am looking for concise, deterministic, pseudorandom function, which is simple enough to have
+comparable overhead when implemented in all the languages. The current `almostPseudoRandom`,
+based on trigonometry, seems to be surprisingly expensive to compute and also gives slightly
+different floating point results in Go version, where it is also 2 times faster than in Java and C.
+
+In the future I will also use this project to test how Kotlin transpiles to native code and
+JavaScript.
+
+I will also rerun these tests from time to time, to check how runtimes and compilers evolve,
+because there are several ongoing efforts for improving memory management and garbage collection in
+many of them.
 
-Any contributions are welcome.
+Any future contributions and optimizations of the current code are welcome. For example if you want
+to contribute a version with custom memory allocator, I would suggest to put it in a separate file,
+instead of extending current code, for better overview how the optimization is achieved. Of course
+if there are any straightforward optimizations, or even justified style changes to the current
+examples, feel free to improve them.
