Execution Strategies - SoftUni-Internal/OpenJudgeSystem GitHub Wiki

What is an Execution Strategy?

Execution strategy in the context of Judge is a class that manages the way a submitted user code will be processed. Depending of the submission type, it sets the execution path a submission will follow, until it returns an execution result, from which the points will be calculated. For every different submission type, from simple block of C#, Java, JavaScript or other language code, to entire solution, database query or plain HTML and CSS, different execution strategy will be in charge of the way a submission is handled by the system.

How it works?

When a lecturer or admin creates a Problem he has to add a bunch of information for the specific problem, which information will be later used to create the "Execution context". The execution context contains information like the tests(input data, expected output, unit tests), memory limit, time limit, the submission type etc. When a user submits it's code or file, depending of the Submission Type, an Execution strategy of type IExecutionStrategy will be created and the submission will be handled by the concrete implementation of this interface by executing the user code under some restrictions and comparing the result to the tests or running the tests against this result, taking in concern the limitations provided from the Execution Context.
