Execution of prolog code is sequential in nature, but one would like to be able to execute multiple algorithm in paralell. Turns out that swi's engine's are quite good att performing this task for us, we can fire up one engine per algorithm and generate answers back and let them …

My next task for guile-log is to make paralell engines store and restorable. This does not work before. In order to see how one can solve this with the already implemented framework, lets first recap paralell engines.

Check out wingo's fibers. I added support for fibers in guile-log and guile-log prolog. Fibers are an attempt to model multitasking, like in erlang, with cooperative scheduling (meaning that you need to enter a sleep now and then to allow other threads to run. Currently the interface is very simplistic …

A recent addition to swi prolog is engines. These objects are self contained prolog engines with their own stack that maintaines the computation state and will generate each answer back stepwise. Guile log have implemented the same API and is reachable from the library

Having had a taste for executing things in paralell in kanren let's move over to guile-log. Executing stuff in paralell is similar but we can take advantage of variable binding beeing done directly on the variable and not bound in a binding data structure. The idea is for each engine …

We will discuss here a kanren version that will modify just partial results and not redo the whole datastructure in order change an underlying value. This means that we are considering paralell executions of code that only modify the data relevant to their code section the solution is a combination …

Swi prolog recently got predicate continuation and knowing of extearamly functional minkanren/microkanren is, one should be able to construct such a beast. Now in most languages you would need to make sure that a cach throw mechanism is working in the return values and somehow knit that together. But …

When coding my prolog VM I noticed that the overhead of a prolog call is in the order of 2M execution per second, and this is typically what I see when executing simple prolog perdicates in swi prolog as well. So all complexity that one need to care for simply …

We are going to explore how set's are handled in guile-log prolog. Lets start off simple.
To define a set just do:
X is {1,2,3}. X = {1,2,3}
We have added common set operators e.g.

Versioning
Consider a variables, a box with a value. Guile-log has the notion of a state. At any point in time all the prolog varibales are bound. And this information can be stored in a state. The guile-log variables are more general than pure prolog variables in that they can be …

Prolog passes all in,out,in/out values as arguments to the predicate. This has the drawback, for out variables, that the variables need to be allocated from the heap and adds complexity and overhead to the predicate. If in stead the out variables could be passed over without making …
