To compute the logical inference algorithm, you need the following:

1. Logical Equivalence: This is a fundamental concept in logic, which states that two statements are logically equivalent if they have the same logical content. In other words, they are either both true or both false under the same set of conditions or interpretations.

2. Validity: This refers to the property of a logical argument where if the premises are true, then the conclusion must also be true. In other words, an argument is valid if it is logically impossible for the premises to be true and the conclusion to be false.

3. Satisfiability: This is a property of a logical formula which states that there is at least one truth assignment to its variables that makes the formula true. In other words, a formula is satisfiable if there exists a model (or interpretation) where the formula is true.

4. All of the mentioned: This means that all the above-mentioned components (Logical Equivalence, Validity, and Satisfiability) are needed to compute the logical inference algorithm.
