A simple game engine with a sample game set in space. The greatest challenge was to overcome
the very limited resources of the hardware, this was also the most rewarding part.
`,
more: [
`
For reducing complexity while maintaining performance, a balance had to be found between object-oriented
and structural programming. For example, a simple prototype-based inheritance is used for the game objects;
meanwhile, an optimised SIMD utilising low-level driver is used for rendering to the display.
I think, the codebase is quite readable and at the same time also fast, with the maximum frame times
being between 15 and 20 milliseconds at a clock speed of 8 MHz. That means, it runs quite stably at 50-60 FPS.
`,
`
As for the hardware, it is quite simple. Aside from the ATtiny85V, a D096-12864-SPI7 display is used for
output and a TSOP4838 for input. The circuit runs on 3.3V, so a regulator is also needed. It uses a current
of 8mA to 11mA on full brightness and around 1.5mA on standby mode.
`,
`
There is also fault-tolerant persistent data storage utilising the built-in EEPROM.
For creating sprites (which are also stored in EEPROM), I made a tool to convert PNG-s into C array definitions.
This can also be found on GitHub along with the entire project.

the contestants could instantly see the effect of their work.

The most interesting aspect of this project was building it in a server-client architecture.
Every decision of the agents is calculated server-side. The real challenge was broadcasting
these decisions in a fault-tolerant way using minimal bandwidth.

The models and animations were also made by me using Blender.

`
In a nutshell, the algorithm (written in Python using NumPy, SciPy, and Flask)
predicts in the frequency domain. The steps are the following: smoothing the input values,
differentiating, applying a short-time Fourier-transformation with overlapped (and Hanning-windowed) windows,
extrapolating and then applying the inverse of these transformations to the resulting values.
`,
`
Of course, there is still plenty of room for improvement, but even with this simple algorithm
a mostly profitable trading strategy is viable. In my free time I may put more work into it.

A simulated system can contain reactors (heaters), coolers, pumps, heat exchangers,
drains, sources, and of course, pipes. With this, simple yet believable configurations

(for layman) a convincingly looking simulation.
`,
`
The algorithm takes advantages of graphs and matrices to get to a next time frame. First,
water flows are distributed by traversing the graph of pipes. Then a matrix is populated
with the relations of the nodes (based on the water flow between them).
After considering the base temperatures and heaters, the matrix is solved resulting in the
current temperature of each node. This can be iteratively continued.

Python is used for the backend along with Flask and NumPy. A REST API facilitates
the communication between the layers. For rendering on the frontend, a HTML5 canvas
is utilised.
