what is a seed in simulation?
3873
A random seed (or seed state, or just seed) is a number (or vector) used to initialize a pseudorandom number generator. For a seed to be used in a pseudorandom number generator, it does not need to be random. ... When a secret encryption key is pseudorandomly generated, having the seed will allow one to obtain the key.

Sowing captures 6 seeds. The 6 captured seeds are resown from the starting hole. Play consists of turns, each move may involve several laps. A player moves by selecting a pit with at least two seeds, and sowing them one by one around their side of the board in a counter-clockwise direction from the starting pit.

“What-if” analysis: Simulation is better suited to observing the performance of the simulated system by tweaking the initial conditions (that is, the values of the input variables). Optimization is used more often to determine an optimal system design. ... Simulation, by contrast, is considered more exploratory.

Simulation, in industry, science, and education, a research or teaching technique that reproduces actual events and processes under test conditions. Developing a simulation is often a highly complex mathematical process.

A seed is living. Although seeds are dormant (resting) their cells are still alive and performing typical cellular functions.

The functionality of the seed arguments are different for $random and $urandom. The seed argument to $random is an inout. It updates its seed argument after each call to $random. ... In SystemVerilog, each thread has its own RNG, so only use the the seed argument on the first call to $urandom in each thread.

A seed is protected by testa and tegmen. Testa is the outer most covering while tegmen is the inner covering.

['Imbibition. The seed rapidly takes up water and the seed coat swells and softens. ... ', 'Interim or lag phase. During this phase the seed activates its internal physiology, cells respire, and the seed starts to make proteins and metabolize its stores of food (MacKean n.d.).', 'Radicle and root emergence.']

The endosperm in a seed develops into the embryo. ... Why do fleshy fruits often have seeds with very tough seed coats? So the seeds can survive the mechanical forces and conditions in an animal's gut. What characterizes the fruit of seeds that are dispersed by the wind?

Viable seeds are living entities. They must contain living, healthy embryonic tissue in order to germinate. All fully developed seeds contain an embryo and, in most plant species, a store of food reserves, wrapped in a seed coat.

Random Number Generators(RNGs) are really generating pseudorandom numbers, since it's impossible to actually generate a TRULY random number. ... When you seed the RNG, you are giving it an equivalent to a starting point. That starting point then has a bunch of numbers that are "inside" of it that the program chooses from.

Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed. The seed protects the embryo and stores food for it.

Seed Round: Refers to a series of related investments in which 15 or less investors "seed" a new company with anywhere from $50,000 to $2 million. ... Series A: Refers to a smaller number of angel investors or VCs who contribute an average of $2-10 million in exchange for equity.

Seed dormancy is defined as a state in which seeds are prevented from germinating even under environmental conditions normally favorable for germination. These conditions are a complex combination of water, light, temperature, gasses, mechanical restrictions, seed coats, and hormone structures.

Simulations are instructional scenarios where the learner is placed in a "world" defined by the teacher. They represent a reality within which students interact. ... Students experience the reality of the scenario and gather meaning from it. A simulation is a form of experiential learning.

The plant embryo, sometimes called the seed embryo, is the part of a seed or bud that contains the earliest forms of a plant's roots, stem and leaves. The embryo develops after a fertilized adult plant flowers, and is generally contained within a seed or bud.

Random number generators can be true hardware random-number generators (HRNG), which generate genuinely random numbers, or pseudo-random number generators (PRNG), which generate numbers that look random, but are actually deterministic, and can be reproduced if the state of the PRNG is known.
