Наверно алгоритм для поиска минимального пути для встречи (оно же кратчайшее время)Yeah, same eggs, side view. The speed is constant ...
Поэтому, я попытался явно выделить основные спорные моменты в вопросах
1 Вопрос. Как лучше, перемещать обе точки или только одну, т.е. обе "ищут" друг друга или одна "ищет" другую ? (скорости одинаковые)
2 Вопрос. Существует ли наилучшая траектория движения, поиска ?
It's still a shadow of a shadow.
Give us the right answer and we'll know it was in the original.
But they must have information about each other. What information do they have about the other's movement? And how do they have the right to move?
The problem has an infinite number of modifications on which the solution depends.
Оба по спирали к центру
Один по часовой, другой против
Либо до встречи
либо до центра
Если центр раньше -разворот
That's exactly what I did )
Но они ж должны иметь инфу друг о друге. Какой информацией о движении другого они располагают? И как имеют право двигаться?
They don't, unfortunately (
None at all? Well, then what is the point of the task?
How will they even know they have met?
Meaning ? Bump into each other, say hello.)
Only two bodies with finite dimensions can collide. But here, they are dots.
It's very possible that the spiral strategy won't help them meet in finite time. In fact, why don't they go straight to the centre?
There ! We can do it when we want to !)
I had no such simplicity in mind )))
Well, that's the point. You haven't described what information they have. Maybe they don't know where the centre of the circle is at all. (By the way, if they don't know, they can't make a spiral either: they won't have a reference point.)
