Why would introducing useless MOV instructions speed up a tight loop in x86_64 assembly?
...Us can probably apply several optimization approaches in parallel and then select the one at the end that provides the best speedup. The extra instructions may be biasing the CPU to use one optimization path that is better than others.
The effect of the extra instructions probably depends on the C...

What is “Argument-Dependent Lookup” (aka ADL, or “Koenig Lookup”)?
...eems a bit backwards. I would expect the problem do be when std::swap() is selected rather than the overload specific to the type, A::swap(). The example with std::swap(A::MyClass&, A::MyClass&) seems misleading. since std would never have a specific overload for a user type, I don't think i...
multi-layer perceptron (MLP) architecture: criteria for choosing number of hidden layers and size of
...
To automate the selection of the best number of layers and best number of neurons for each of the layers, you can use genetic optimization.
The key pieces would be:
Chromosome: Vector that defines how many units in each hidden layer (e.g....

...tlook. I then used the signature editors "replace image" functionality to select a local file (instead of the base64 encoded image I had manually included). This seems to do what you mean. Thanks for sticking with me.

Undefined behavior and sequence points
...er: that reason is concurrency. Unspecified order of elaboration is merely selection of one of several possible serial orderings, this is quite different to before and after orderings, because if there is no specified ordering, concurrent evaluation is possible: not so with the old rules.

How is the current ring determined?
The current ring is selected by a combination of:
global descriptor table: a in-memory table of GDT entries, and each entry has a field Privl which encodes the ring.
The LGDT instruction sets the address to the current descriptor table.
