The OpenCog (hyper-)graph database and graph rewriting system
I have the following problem: there are many objects (few thousands) on the scene. It is required to find closest red object for each object on the scene. After reading...
# Object Proposal for an hypergraph type checker. # Motivation The current type system is too limiting and doesn't allow to overload operators. Here's an example when using PLN Or/And...
## Overview Currently the only way to create new atom types is at compile time via C++. It could be useful to allow the creation of new types at run-time...
I try to execute the following example: ```scm (define (filter atom) (display "filter called ") (display atom) (newline) (SimpleTruthValue 1 1) ) (cog-execute! (Map (ImplicationScope (TypedVariable (Variable "x") (Type "ConceptNode"))...
As suggested by @vsbogd in https://github.com/opencog/atomspace/pull/1774#issuecomment-400259218 it could be good to have some level of normalization at insertion time (whenever it makes sense, i.e. the non-normalized form is never desired)....
The problem of `ListLink` (as well as `SetLink`) is that it allows to construct atoms with an arbitrary large outgoing set. There are 2 problems with that 1. Dealing with...
The expression `(NotLink (ChoiceLink single-atom))` should be equivalent to `(AbsentLink ingle-atom)` but will almost surely fail in the current implementation. Note this is closely related to issue #215 Just like...
This issue is to discuss plan of removing unnecessary double atoms creation which were discussed at issue #1965, especially in comments: - https://github.com/opencog/atomspace/issues/1965#issue-393676171 - https://github.com/opencog/atomspace/issues/1965#issuecomment-449579254 - https://github.com/opencog/atomspace/issues/1965#issuecomment-449588049 - https://github.com/opencog/atomspace/issues/1965#issuecomment-449594328 At...
Create a backwards-compat mode for gremlin/tinkerpop. Or at least steal some ideas from there.
I am trying to decide between a couple of options of how to structure the Histograms used for DVs and failing. So I'll be explaining all the options that I...
