so on, they will also comment and follow each other. Next, you just need to pay attention to them and see what results are related to yourself.
Generally speaking, to understand a domain, you need to start from the following aspects: patents, papers, blogs, and the homepage of research institutions.
If you study patent open classes, you will not post the papers. You can search for them directly by google or on the internal network of the school.

Although the design circle is popular not to "repeat the wheel" argument, but beginners still need to learn from the bottom to the top of the robot's entire design process, and then find themselves interested in or good at a certain direction to dig deep, become an expert (not brick house ha).2.

Asimov invented the term robotics, and proposed the three principles of robotics, and then in these three simple design principles based on the creation of a series of classic works-about 50 books.

. In the field of control theory, robotics, operations research and economics, there are still many scholars who devote themselves to the research of RL, and similar concepts or algorithms are often re-invented in different fields and have different names.The development of RL is influenced by many disciplines [31]Princeton University's famous research operations expert Warren Powell once wrote an article titled AI, OR and Control theory:a Rosetta Sto
Microsoft robotics Studio 1.0 is released. Microsoft robotics studio is a development environment that uses Micrsoft Visual Programming Language (VPL) for Robot programming. There may not be many people familiar with robot programming, there will be fewer people with robots .. so let's start with robot programming to see what VPL looks like:

enforcedArrayblockingqueue: Bounded task queue, the Arrayblockingqueue constructor must take a capacity parameter (for example, N) to indicate the maximum capacity of the queue.When a new task executes, this defines the current number of threads as T, the capacity parameter of the constructor is N, and the current queue length is L1.t2.t>corepoolsize and L3.t>corepoolsize and L>=n, create a new thread to perform a new task4.t>maximumpoolsize, the Deny policy is enforced.Linkedblockingqueue:

Oracle provides a clause for this situation: rows between... preceding and... following. Literally, I guess it means that all records before and after XXX let us verify through examples:

number of threads set by maximumPoolSize is reached, a denial policy is executed.
ArrayBlockingQueue: A Bounded task queue. The ArrayBlockingQueue constructor must contain a capacity parameter (for example, n), which indicates the maximum capacity of the queue.
When a new task is executed, the current number of threads is defined as t. The capacity parameter of the constructor is n, and the length of the current queue is l.

This policy allows the possibility of an increase in the number of lines that are allowed to continue when the command arrives in a row that exceeds the average that the queue can handle.unbounded queues. using unbounded queues (for example, linkedblockingqueue that do not have a predefined capacity) will cause all corepoolsize threads to
unbounded queries that perform well over small test data sets may degrade sharply against real data. if you don't manage your precious DBMS and memory resources, your problems will only compound under load.
Efficient data retrieval and paging is a trade-off between memory usage and response-time requirements. Broadly speaking, most roll-your-own J2EE paging mechanic ISMs fall into two basic categories:
