ass(..., Strategy => ...) -- specify a computational strategy

ass(..., Strategy => ...) -- specify a computational strategy

The strategy option value should be one of the following.

1 -- The assasinator is found using Ext modules.

2 -- The assasinator is found using top on a series of ideals.

The default strategy is 2.

Strategy => 1

The associated primes are found using the Ext modules: The associated primes of codimension i of I and Ext^i(R^1/I,R) are identical, as shown in Eisenbud-Huneke-Vasconcelos, Invent math, 110, 207-235 (1992).

Strategy => 2

The associated primes are found by iterating the two steps: take the minimal primes oftop of the ideal, I, and replace I by I:(top I).
