Indirect methods of automatic memory management are those in which the information necessary to determine whether an object can be reclaimed is not stored in or associated with that object, but is derived from other objects. Indirect methods detect garbage by tracing reachable objects. Indirect methods cannot always reclaim memory as soon as it becomes dead, because it may be necessary to inspect many other objects to determine this. However, not having to store and update information on each object may reduce the overhead for the collector. In distributed garbage collection, this can reduce the amount of communication between processors. Similar terms: tracing garbage collection. Opposites: direct method. Related publications
(n.) Any technique for solving a system of equations that does not rely on linear algebra directly. Successive over-relaxation is an example of an indirect method. See also direct method.
A method for checking the validity of a sequent in SL. In this method we first assume that the argument is invalid, and proceed to find an invalidating assignment. If this turns out to be impossible, then the argument is valid. Otherwise it is not.

A method of calculating cash flow which uses the starting point of operating profit, since it is the operating activities of sales and costs that normally give rise to the majority of cash inflows and cash outflows of an entity. Operating profit for the period must then be adjusted for depreciation, as well as movements in stock, debtors and creditors over the same period to derive the net cash flow from operating activities.
For preparing the Operating Activities section of the statement of cash flows, the approach in which net income is reconciled to net cash flow from operations.
A method of reporting net cash flow from operations that involves converting accrual-basis net income to a cash basis.
