| Personal service, as reiuqred in the bill, would establish a higher standard of service for paternity actions than all other civil actions. This higher standard does not directly address paternity fraud or prevent fraud in the future but instead would adversely impact the establishment of paternities. Thousands of paternity judgments are established timely each year by serving individuals by substitute service or by mail. The bill’s requirement of personal delivery service would severely delay this process, but more important, would provide biological fathers the ability to evade service of process [my emphasis], preventing the establishment of paternity in the majority of these cases and allowing the avoidance of parental responsibilities. This would directly impact child support collections and would jeopardize California’s ability to meet federally reiuqred performance measures putting California at risk of losing up to $40 million in federal funds. [emphasis added]In addition, AB 2240 has substantial federal compliance problems that would adversely affect California. The bill’s requirement of a paternity questionnaire, signed by themother, would prevent the filing of a paternity action in cases against the father if the mother is deceased or unavailable, or if she simply refuses to cooperate. This would prevent moving ahead on cases even if other evidence establishes paternity. This would also apply to foster care cases where federal law requires the establishment of paternity and child support. AB 2240 would prevent California from proceeding on a large number, if not most, of foster care cases, putting California out of compliance with federal law.This is about money. Many states depend upon federal grants to support their child support systems. If the states can't declare the guys these whores are married to to be the fathers of those bastard children, then they can't declare any guy to be the father of those bastard children when the actual father isn't known. That means states lose tens of millions of dollars in federal grants - which means those states have to raise taxes to pay for the welfare that those women will surely need...because those women are going to need it when their husbands divorce them and they're left to pay for those kids on their own.This is about money. It's that simple. And that money is going to come from somewhere. And, as former-governor Gray Davis made clear, the rights of the victims don't matter. | max(2x1 + 5x2 + 4x3) 2x2 <=4 x1 + x3 <= 2 2x1 + x2 + 2x3 <=3 x1 + 2x2 <=6 x1, x2, x3 >=0 |

Nenašel jsem žádné lepší. Takže zatím nejlepší řešení. ** 2) výpočtem dle cvičení Fialy (cviceni cislo 12)** Stručně: A) vektor b ( vektor pravých stran) obsahuje záporné koeficienty => pokud nyní sestavíme simplexovou tabulku, nebude výchozí bázické řešení přípustné, jelikož nám výjde že nějaká bázický proměnná má hodnotu menší než nula B) tudíž musíme najít jiné výchozí bázické řešení, které bude připustné a to pomocí pomocné úlohy - jeji optimalni reseni - viz cviceni - C) při návratu k původní úloze je potřeba účelovou funkci přizpůsobit - uvést simplexovou tabulku do konzistentního stavu - tj. jednak bázické sloupce musí v účel. fci mít hodnotu 0 A pak bazicke reseni musi byt pripustne - coz ziskame z pomocne ulohy z B) D) nyni uz pokracujeme v reseni puvodni ulohy simplecovou metodou Timto zpusobem se podari vypocitat: Optimalni reseni: (x1=4,x2=1,x3=2; uc. fce= 5), (takze jako kalkulackou) --- Omlouvam se za nepresnosti, nicmene nemel bych se nikde dopustit lzi.
