How do you determine the order of tasks with different levels of complexity?

To determine the order of task execution with varying levels of complexity, I usually apply the following approaches:

• Prioritization by importance and urgency: I first perform tasks that are critical to the project or have strict deadlines.
• Assessment of effort: if a task is complex and requires a lot of time, it can be broken down into subtasks and planned to be completed in stages.
• Use of planning methods: for example, the Kanban or Scrum method, where tasks are sorted by priority and complexity.
• Considering task dependencies: tasks that other tasks depend on are performed first.

An example in Java using a priority queue:

import java.util.PriorityQueue;

class Task implements Comparable<Task> {
    String name;
    int complexity; // the higher, the more complex

    public Task(String name, int complexity) {
        this.name = name;
        this.complexity = complexity;
    }

    @Override
    public int compareTo(Task other) {
        return Integer.compare(this.complexity, other.complexity);
    }
}

PriorityQueue<Task> taskQueue = new PriorityQueue<>();
taskQueue.add(new Task("Simple task", 1));
taskQueue.add(new Task("Complex task", 5));

while (!taskQueue.isEmpty()) {
    Task task = taskQueue.poll();
    System.out.println("Executing: " + task.name);
}

Here, tasks with lower complexity will be executed first. In real projects, priorities may also consider other factors.
