NOTE:

Some of these bots rely on Python/Numpy random. User results may differ from developer results. As of this time in writing, developer Python version is 3.14.2.

NOTE:

The methods provided in file<graph_problems.easy_gen> allow for easy generation of these bots (less instantiating parameters).

The Machine-Learning Aspect

The graph problems defined in this project involve software agents. These agents are programmed with functionalities that are static. This implies the agents cannot "learn" any more, past their programming, about the specific problems they act in. Their learning mechanisms cannot "expand" any more outside of this static programming: no additional variables of interest, no different data structure formats, no different ordering scheme of deciding on the best choice per timestamp, no different ranking mechanisms for choices. Instead, the only way to improve a solution is through a semi-blind search process that iterates through a candidate list of pseudo-random number generators (PRNGs) for the best PRNG. PRNGs are used in agent decision-making for these graph problems. PRNGs output numbers, and agents map these numbers out to decisions taken by them. The utility of obtaining a high-performing PRNG for a graph problem of specific starting parameters is restricted to that case. There is no software mechanism provided to automate deriving of further insight into any graph problem example via a high-performing PRNG. This deficit differs from traditional machine-learning problems on fixed and labeled datasets, where feedback loops of training iterations can be guaranteed to yield incrementally better solutions, until the global optimum is found. This guarantee, of course, is theoretical and cannot be stated for deep learning problems on highly variable datasets. It is possible to implement further code for these graph problems to be more conducive for machine-learning. However, implementing further code would defeat the purpose of graph problem difficulty. The division of partial information between agents in every one of these graph problems was deliberate in fulfillment of maintaining a baseline of probabilistic difficulty for an agent to improve its solution (PRNG). Unlike the highly vectorizable (input,output) samples of traditional machine-learning that typically operates in Euclidean space, finding a high-scoring solution does not easily lead to a better solution derived from that one. Users can refer to one high-scoring PRNG, and add tweaks to it at selected indices of the generator output. See below for illustration on PRNG G and tweaking it to G2:

G:  x0,x1,x2,x3,x4,x5... 
G2: x0,x42,x2,x56,x4,x5,... 

But this is a cumbersome process, and there is no guarantee making tweaks to a high-performing generator would result in a better solution.

User Access to the Graybox

The computer code for these bots in these graph problems is open for view. This is not a blackbox arrangement. Users, in their attempts to guess high-performing PRNGs for any graph problem example, can carefully review how the automata decision-making pipelines work. These pipelines follow a general form, and descriptions are provided for each of these graph problem bots. But these implementations rest on arbitrary design.

In a blackbox system, users would not know what the graph problem is, let alone the general form of it. They would only be able to enter in a PRNG for the automaton to use for decision-making. They would not be able to ascertain the end results from the PRNG. In these graybox implementations, users would know the end results from the PRNG. But since a PRNG only outputs real numbers for decision-making, users would not be able to easily know what decisions the PRNG was responsible for. Thus, users would have a relatively difficult time knowing what decisions are sub-optimal. Users can analyze the code implementation to determine the specific decisions the PRNG mapped to, post-simulation. But code is not provided in this project to convenience that.
