+I decided to write this protocol in simple markdown, as I find it the easiest.
+To view it with the images rendered, you will need a markdown viewer on your system.
+
+Alternatively, you can see it rendered on my Forgejo page for this repository:
+https://git.itsdrike.com/ap8mi/task2
+
+You can also look at the images directly, they're in the `imgs` directory, and their
+file names do a fairly good job at explaining the settings used.

+# Protocol
+
+In this task, we were supposed to implement two optimization algorithms in an effort to find the minimum value of the
+functions that we've worked with in the last task. The two algorithms were Local Search (LS) and Stochastic Hill
+Climbing (SHC). Both of these are pretty similar, the only difference between them is that the LS algorithm includes the
+center point when determining the minimum, while the SHC algorithm only considers the new points.
+
+From my testing, the SHC algorithm usually performed worse with the same amount of iterations, because LS was more
+focused on exploring the lowest point of the minimum, while SHC often didn't and instead jumped elsewhere.
+
+That said, because of this fact, SHC actually performed better in cases where LS got stuck in a local minimum, as LS
+can't recover from this, while SHC can.
+
+## Output (graphs)
+
+Below are a few examples of the runs I performed:
+
+### Sphere
+
+I first ran the algorithm on the sphere function, with the following settings:

+
+For Local Search, this was the resulting graph:

+
+For Stochastic Hill Climbing, the result was this graph:

+
+### Rosenbrock
+
+Next, I tried the Rosenbrock function, with the following settings:

+
+For LS, I got:
+
+![img](./imgs/2_ls.png)
+
+For SHC, I got:
+
+![img](./imgs/2_shc.png)
+
+### Further experimenting with Rosenbrock
+
+I also tried adjusting some of the settings with the Rosenbrock function, to compare how they affect the LS and SHC
+algorithms. Each time, I only modified a single settings, with the rest matching the original Rosenbrock configuration
+(already shown above).
+
+#### 1000 iterations
+
+I first tried increasing the number of iterations to 1000 (from 30).
+
+For LS, I got:
+
+![img](./imgs/2_ls_iterations-1000.png)
+
+for SHC, I got:
+
+![img](./imgs/2_shc_iterations-1000.png)
+
+#### 100 neighbors
+
+I then tried increasing the amount of neighbor points to 100 (from 3).
+
+For LS, I got:
+
+![img](./imgs/2_ls_neighbors-100.png)
+
+for SHC, I got:
+
+![img](./imgs/2_shc_neighbors-100.png)
+
+#### Standard deviation of 30
+
+Finally, I tried increasing the standard deviation of the normal distribution to 30 (from 1.5).
+
+For LS, I got:

+
+for SHC, I got:
