Public predicates

.. index:: mutation/3 .. _mutations_store/0::mutation/3:

mutation/3 ^^^^^^^^^^^^^^

Returns a random mutation of a term into another term of the same type. The input Term is assumed to be valid for the given Type.

| Compilation flags: | static

| Template: | mutation(Type,Term,Mutation) | Mode and number of proofs: | mutation(@callable,@term,-term) - one

---

.. index:: counter/2 .. _mutations_store/0::counter/2:

counter/2 ^^^^^^^^^^^^^

Table of the number of mutations available per type.

| Compilation flags: | static

| Template: | counter(Type,N) | Mode and number of proofs: | counter(?callable,?positive_integer) - zero_or_more

---

Protected predicates

(no local declarations; see entity ancestors if any)

Private predicates

.. index:: mutation/4 .. _mutations_store/0::mutation/4:

mutation/4 ^^^^^^^^^^^^^^

Returns a random mutation of a term into another term of the same type using mutator N. The input Term is assume to be valid for the given Type.

| Compilation flags: | static, multifile

| Template: | mutation(Type,N,Term,Mutation) | Mode and number of proofs: | mutation(?callable,?positive_integer,@term,-term) - zero_or_more

---

.. index:: counter_/2 .. _mutations_store/0::counter_/2:

counter_/2 ^^^^^^^^^^^^^^

Internal counter for the number of mutations available for a given type.

| Compilation flags: | dynamic

| Template: | counter_(Type,N) | Mode and number of proofs: | counter_(?callable,?positive_integer) - zero_or_more

---
