将Leonard Esau Baum（伦纳德·伊索·鲍姆）的Baum–Welch（鲍姆－韦尔奇算法模型）进行改进，扩展，分段微分化+股神Warren Edward Buffett 的传统价值投资理论。

对Elias=Jerome来说，Leonard Esau Baum（伦纳德·伊索·鲍姆）的Baum–Welch（鲍姆－韦尔奇算法模型）+股神Warren Edward Buffett 的传统价值投资理论 就是金融市场上的MG42机关枪。特征为高速高效，具有类似“撕裂布匹”的枪声，空头称之为“夺命电锯”，此外同时具备可靠性、耐用性、简单化、容易操作以及成本低廉等特性。Elias=Jerome虽然是学理论物理和应用数学的。坦率地说，套利平台Leonard Esau Baum（伦纳德·伊索·鲍姆）的Baum–Welch（鲍姆－韦尔奇算法模型）中的有些东西，比如静态参数，动态参数，泛函，非函等的计算和设置，没有完全搞懂。似乎只有搞纯数学的才能彻底弄懂，James Harris Simons已经公开说了那是他们核心机密，无可奉告。另外，Elias=Jerome对计算机软件方面是很弱的，很多iOS软件的使用都不知道，更别提编写和架构软件程序了。

The MG42 is characterized by its extremely high rate of fire, up to 1,500 rounds per minute. When firing, unlike other machine guns, it makes a sound similar to "tearing cloth". The Allies called it "Hitler's chainsaw". In addition, it also has the characteristics of reliability, durability, simplicity, easy operation and low cost.

The MG 42 (shortened from German: Maschinengewehr 42, or "machine gun 42") is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II.

Designed to use the standard German fully-powered 7.92×57mm Mauser rifle round and to be cheaper and easier to manufacture, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges: it averaged about 1,200 rounds per minute, compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the M1919 Browning, FM 24/29, or Bren gun. This made it extremely effective in providing suppressive fire. Its unique sound led to it being nicknamed "Hitler's buzzsaw".

MG42的特点是射速极高，最高可达每分钟1500发。射击时，与其他机枪不同，它会发出类似于“撕布”的声音。盟军称其为“希特勒的电锯”。此外，它还具有可靠、耐用、简单、易操作和低成本的特点。

MG 42（德语缩写：Maschinengewehr 42，即“机枪42”）是德国后坐式风冷通用机枪，在二战后半期被德国国防军和武装党卫队广泛使用。它于1942年开始生产，旨在补充和取代早期的MG 34，后者价格更昂贵，生产时间更长，但这两种武器都生产到二战结束。

MG 42 的设计目标是使用标准的德国全功率 7.92×57 毫米毛瑟步枪子弹，而且制造成本更低、更简单，因此被证明非常可靠且易于操作。它最引人注目的是，对于使用全功率制式弹药的枪来说，它的循环速率非常高：平均每分钟约 1,200 发，而 MG 34 约为 850 发，其他常见机枪（如 M1919 勃朗宁、FM 24/29 或布伦机枪）为 450 至 600 发。这使得它在提供压制火力方面非常有效。它独特的声音使它被昵称为“希特勒的圆锯”。

Elias=Jerome只能另辟新径，扬长避短，扩大容错空间，有容乃大。根据实际参数情况进行有效地校验，然后两者巧妙地互相融合，定性分析与定量分析兼顾，相辅相成，相得益彰，有原则更有灵活才是王道和王牌。
